Question about 1999 Jeep Cherokee

1 Answer

Using a multi meter how can I determine which fuse blocks are open or have the proper amp fuses installed ?

Going through the factory manual I've noticed the fuse block has many
OPEN circuits when I checked mine some of these had fuses in them,some rated blocks had weaker or stronger fuses in them ? Now (with me messing with this)the CHECK ENGINE light came on showing my cooling fan code and tranny code. help me solve this?

Not really following your line of questions.
You can check to see if a circuit is hot by grounding a meter or test light and touching the positive lead to the fuses. You would have to go by the book as to the size of each fuse.
If you pull a fuse with the key on you can disable a circuit or system such as the cooling fan which would turn on the check engine light.
You would turn the light off by erasing the code with a scanner.

A common problem on many of the new cars is that when a person gets gas, they don't tighten up the gas cap. This will turn on the check engine light. Did you get gas recently? Another option is to see what code is stored in the ECU that turned the light on. This is done with a scanner tool. If you do not have a scanner, then have a dealer look at it.

No its not true,the cooling fan comes on when the coolant temp reaches a certain point it closes the switch in the temp sensor wich in turn closes the relay and powers the cooling fan,the reason it comes on with the A/C is that it's wired to bypass the temp sensor and associated relay because the A/C compressor forces the motor to work harder and the coolant temp to rise significantly faster,the relay needs to be replaced or you will overheat the motor and possibly cause serious damage.

SOURCE: Radio and interior lights will not work.

"No fuse" in the odometer means the IOD (ignition off draw) fuse is either missing or blown. It supplies power to the interior lights as well as memory functions of some modules while the key is off. It is to be removed for extended periods of storage so not to run the battery down.

Your engine computer is bad. It's a good thing that you mentioned about the check engine light dying also, as this is a classic sign of a bad ecm. I have repaired more than one of these Jeep computers, replacing the three power capacitors located inside the computer, and they have worked for years afterwards. If you don't have the skills or knowledge to repair the ecm, get yourself a rebuilt ecm unit and swap it out.

No air from vents, cant hear motor working ford focus


Hi Victoria,

Your car's electrical components, like those in your home; are protected by fuses and / or circuit breakers.

You car has two fuse boxes. One is located under the hood (in the engine compartment) and the other in in the passenger compartment. Some popular locations are under the dashboard, in the dashboard behind a removable cover, under a seat, etc. Consult your owner's manual to determine the location for your car.

Once you have located the fuse block, you will need to determine which fuse is associated with the heater / AC fan, as there are dozens of fuses in the fuse block. The protective cover usually has a directory of fuse size, locations and function. If yours lacks such a directory - your manual will have it. It is not unusual for several directory pages in the manual, as the manual may cover several versions of the Ford Focus. If this is the case with yours, be sure to look at the page(s) for your version Ford Focus.

Once you've located the suspect fuse, remove the fuse with a tool that may be provided on the cover, etc. or other tool. The fuses are made of hard plastic, and are generally pretty durable - but can break if crushed in a tool. After removal, look for the shiny metal inside the plastic. It should appear unbroken along its entire length. If it is broken, it has opened. The plastic should not have any black areas inside - if so, it indicates the fuse has blown. Either of the conditions indicates that the fuse should be replaced. Replace the fuse with a new one. Fuses are color coded by amperage, be sure to use the same color fuse or fuse value. Do not increase or reduce the fuse value.

After changing the fuse, test the fan to see if it works. If it does, close everything up & discard the old fuse - you're done. Otherwise, double check the fuses to be sure you've changed the right fuse, etc. You may need to have the car service professionally if the fan motor or control has failed, etc.

I hope this helps & good luck!

Sunroof won't respond to controls on '93 Nissan Quest


It's either the switch or fuse or motor or rusted. Look in your car manual for "fuse box(es)' and follow the diagram and legend of your fuse panel. Or you can check each fuse to find a burnt out one and replace them. Sun roofs still working in "93's is a good design. If it has not been used for a season, you can try to help it when your activating switch. It could also be rust/corroding and needs to be freed up from it sitting position. When it opens get some good lubrication on the moving parts non conductive quality for electro parts. After you've check the fuse, switch, the motor will be hard to access to test it. So determine if it is NOT leaking, now do you want to chance it not sealing properly and leaking from your fuddling with it?

Interior fan want work


First, check the fuse block for an open / blown fuse. You didn't provide the make & model of your car, so you'll have to find out which fuse is used for the fan. Replace any open / blown fuse found with the correct size as determined by the manual. If it still doesn't work, keep reading:

Many cars and trucks use what is called a "resistor pack" that is used to determine various preset speeds for the heater & A/C blower or fan. When you switch the fan from one speed or another, power is passed through a different value of the resistor - which changes the voltage to the fan motor. The different voltages provides different speeds.

The resistor pack is usually the problem if the fan works at one or more - but not all speeds. It can be the problem if the fan doesn't work at all either. The location of the resistor pack varies with vehicle make and model, but is often very close to the motor itself and accessible from the passenger compartment. Consulting with a employee at an auto parts store or Chilton's (or similar) auto repair manual should get you to the right spot. Resistor packs are relatively inexpensive at about $25 or less.

I hope this helps & good luck!

My windows won't go down or up, my fuse gets super hot when i turn on the engine, i changed the switches on all the windows and and the 30 amp fuse what can i do now. do i need to change the windo


If all of them don't work after changing the switches and the fuse gets supper hot you need to double check your work. It sounds like you put a short some where in your circuit . The other thing is to check the switches with an ohm meter. This is to see what the switch is doing. Normally open or normally closed. If by accident that the factory gave you a bad part such as a short in the switch. I am assuming that the only way to hook up your switch is with the socket that came with the car. Your not plugging in each wire to the switch block.

In the instrument panel fuse block there should be a fuse labeled RDO/INT LP. that is the radio and interior lamp fuse. If you have a factory stereo with a factory amp there will also be a fuse labeled AMP in the same fuse lock. Let me know if you have any questions and I'll do my best to answer them.

2006 kia sedona a/c keeps blowing fuse


Not unless you are willing to risk electrical damage or a fire! A fuse is a protection device that is designed to blow if the amp load in a circuit exceeds the "safe" limit for that circuit. Fuses are built with a specific amp rating which is marked on the fuse. The wiring and design load of the circuit dictates the size of fuse that's required to protect the circuit. Circuits that draw a lot of power need fuses with high amp ratings (20 or 30 amps) while those that use minimal power require smaller fuses (5 to 15 amps).

When the current in a circuit exceeds the normal limit for whatever reason, the metal element in the fuse melts and opens the circuit stopping the flow of current. A short, for example, causes a runaway electrical current. If not stopped, wires can start to melt and things can catch on fire. So respect the amp ratings specified for fuses (which can usually be found in your vehicle owners manual, on the fuse block itself or a fuse block reference decal).

What happens if you install a fuse with the wrong amp rating? If you install a 20 amp fuse in a circuit designed for 10 amps, you're asking for trouble. A difference of 10 amps might not sound like much, but it may be enough to fry a sensitive electronic component or to overheat wires to the point where the insulation may start to melt.

WARNING: Under no circumstances should you ever bypass or eliminate a fuse. No electrical circuit should ever be operated without fuse protection. This is extremely dangerous, especially if you've had problems with a fuse blowing before.

If a fuse keeps blowing, it usually means something is amiss in the circuit. The wiring should be checked along with the components in the circuit to determine if there's a short or other problem.

The fuse for the windshield wiper circuit, for example, may blow if ice or debris builds up in the cowl areas and interferes with the movement of the wiper arms. If a fuse blows in a motor circuit (heater blower motor, cooling fan motor, power seat or window, electric fuel pump, etc.), it often indicates a shorted motor. If a fuse in a light circuit blows, look for wiring or connector shorts. Adding driving lights may also overtax the headlight circuit unless a separate circuit is provided for the driving lights. An A/C fuse will blow if the system is low on refrigerant and is working unusually hard, or if the compressor is hanging up. Stereo systems with high amp boosters should also have their own electrical circuit with fuse protection to avoid overloading the normal radio circuit.

My 1988 Plymouth horizon had some gas put in it that was mixed with 2 cycle oil and then it was ran out of gas totally. I get some gas put in it and it has just spit and sputtered and been messed up ever...


What you have there sounds strange to say the least. The codes seem unrelated. (ignore 55...that is just the end of code string). Before going any further check every fuse and fuse socket to make sure everything is good there. Don't bother identifying the fuses just check them. ALL....ones under the dash AND the ones in the power distribution center. have you tested the MAP sensor both for vacuum and electrically? There are individual component tests you can do using a digital multi meter. Instructions are in chilton or haynes manuals. (manual and meter probably cost less than half what you've spent already). If you find nothing then you will need to "pin out" the wiring from the computer and make sure everything is getting to and from it properly and also Why not test that O2 sensor and make sure the converter isn't plugged? You can often clear the injectors by putting 4oz of acetone per 10 gallons of fuel into the gas tank. I can't write out instructions for all the tests but if it ran well before you added the chainsaw fuel (which normally does little or no permanent damage), you are probably missing something simple. I can't tell you what it is only because I can't see it!!!

I change the bulb (9007) and it still womt work


Using a multi-meter, check for 12 volts when the light is supposed to be on. If 12 volts is not present, you may have a faulty terminal, faulty wiring, faulty switch, or blown fuse. It is also possible that the bulb was DOA, or damaged prior to installation or during installation. Check the bulb for an Open Line using a multi-meter. Replace the bulb if it is an open line.

I have a slow battery drain on a 2006 Jeep Liberty. Pulling either fuse #34 from the dash fuse box or #7 under the hood (labeled JB Power) will eliminate the drain. According to the owner's manual #34...


Hi
Welcome
Jb power is Junction Block power
Here is a list of tests for this problom

IGNITION-OFF DRAW TEST The term Ignition-Off Draw (IOD) identifies a normal condition where power is being drained from the battery with the ignition switch in the Off position. A normal vehicle electrical system will draw from five to thirty-five milliamperes (0.005 to 0.035 ampere) with the ignition switch in the Off position, and all non-ignition controlled circuits in proper working order. Up to thirty-five milliamperes are needed to enable the memory functions for the Powertrain Control Module (PCM), digital clock, electronically tuned radio, and other modules which may vary with the vehicle equipment.
A vehicle that has not been operated for approximately twenty days, may discharge the battery to an inadequate level. When a vehicle will not be used for twenty days or more (stored), remove the IOD fuse from the Junction Block (JB). This will reduce battery discharging.
Excessive IOD can be caused by:
  1. Electrical items left on.
  2. Inoperative or improperly adjusted switches.
  3. Inoperative or shorted electronic modules and components.
  4. An internally shorted generator.
  5. Intermittent shorts in the wiring.
If the IOD is over thirty-five milliamperes, the problem must be found and corrected before replacing a battery. In most cases, the battery can be charged and returned to service after the excessive IOD condition has been corrected.
1. Verify that all electrical accessories are off. Turn off all lamps, remove the ignition key, and close all doors. If the vehicle is equipped with an illuminated entry system or an electronically tuned radio, allow the electronic timer function of these systems to automatically shut off (time out). This may take up to three minutes. See the Electronic Module Ignition-Off Draw Table for more information.
ELECTRONIC MODULE IGNITION-OFF DRAW (IOD) TABLE Module Time Out?
(If Yes, Interval And Wake-Up Input)
IOD IOD After Time Out Radio No 1 to 3 milliamperes N/A Audio Power Amplifier No up to 1 milliampere N/A Central Timer Module (CTM) No 4.75 milliamperes (max.) N/A Powertrain Control Module (PCM) No 0.95 milliampere N/A ElectroMechanical Instrument Cluster (EMIC) No 0.44 milliampere N/A Combination Flasher No 0.08 milliampere N/A 2. Determine that the underhood lamp is operating properly, then disconnect the lamp wire harness connector or remove the lamp bulb. 3. Disconnect the battery negative cable. 4. Set an electronic digital multi-meter to its highest amperage scale. Connect the multi-meter between the disconnected battery negative cable terminal clamp and the battery negative terminal post. Make sure that the doors remain closed so that the illuminated entry system is not activated. The multi-meter amperage reading may remain high for up to three minutes, or may not give any reading at all while set in the highest amperage scale, depending upon the electrical equipment in the vehicle. The multi-meter leads must be securely clamped to the battery negative cable terminal clamp and the battery negative terminal post. If continuity between the battery negative terminal post and the negative cable terminal clamp is lost during any part of the IOD test, the electronic timer function will be activated and all of the tests will have to be repeated. 5. After about three minutes, the high-amperage IOD reading on the multi-meter should become very low or nonexistent, depending upon the electrical equipment in the vehicle. If the amperage reading remains high, remove and replace each fuse in the Power Distribution Center (PDC) , one at a time until the amperage reading becomes very low, or nonexistent. (Refer to 04 - Vehicle Quick Reference/Fuse Locations and Types - Specifications) for the appropriate wiring information for complete PDC and TIPM fuse, circuit breaker, and circuit identification. This will isolate each circuit and identify the circuit that is the source of the high-amperage IOD. If the amperage reading remains high after removing and replacing each fuse and circuit breaker, disconnect the wire harness from the generator. If the amperage reading now becomes very low or nonexistent, diagnose and repair the Charging System as necessary. After the high-amperage IOD has been corrected, switch the multi-meter to progressively lower amperage scales and, if necessary, repeat the fuse and circuit breaker remove-and-replace process to identify and correct all sources of excessive IOD. It is now safe to select the lowest milliampere scale of the multi-meter to check the low-amperage IOD.
CAUTION: Do not open any doors, or turn on any electrical accessories with the lowest milliampere scale selected, or the multi-meter may be damaged.

6. Observe the multi-meter reading. The low-amperage IOD should not exceed thirty-five milliamperes (0.035 ampere). If the current draw exceeds thirty-five milliamperes, isolate each circuit using the fuse and circuit breaker remove-and-replace process in Step #5 . The multi-meter reading will drop to within the acceptable limit when the source of the excessive current draw is disconnected. Repair this circuit as required; whether a wiring short, incorrect switch adjustment, or an inoperative component is the cause.
