Your blower motor has a resonator that can fail and cause this...try disconnecting the blower motor to confirm the resonator is bad...should be located in a box on the fire wall...

98 Jimmy has a power draw it kills the battery within 12 hrs if you pull the 50 amp fuse for the int batt draw goes away any ideas


Yes Steve I do , that fuse supply's power to the I/P fuse block inside the vehicle . It powers AUX/PWR fuse #13 -20amp , RDO/BATT fuse #19 - 15amp ,MIR/LKS fuse #7 - 5amp , CTSY/LP fuse #8 - 15 amp , CIGAR/LTR fuse #2 15 amp , PWR/LKS fuse #14 15 amp , HDLP/SW fuse #1 - 10amp .Do you know where the I/P fuse block is ? You would need to do a parasitic draw test ! This involves hooking up a amp meter in series with the negative battery post an negative battery cable . Pulling each one of these fuses till the battery draw stops ! How To Perform Parasitic Draw Test EricTheCarGuy check out Eric the car guy's video on the subject !

Something pulling battery down on 1990 olds 98


You may need to test for a parasitic power drain, for example a horn switch that is stuck closed causing the horn relay switch to stay on continuously even if the wire was unplugged from the horn.

You will need multimeter to test for a parasitic power drain.

1. With the key off, disconnect the negative battery cable.
2. Connect the black multimeter test lead to the negative battery post, connect the red test lead to the negative battery cable.
3. With the meter set to the DC milli-amps scale note the current draw displayed. If it is over 20 mA, there is likely something drawing power that shouldn't be.
4. Leaving the meter connected have an assistant pull fuses one at a time (replacing them before pulling the next) until the meter reading drops. The circuit that this fuse powers is where the problem most likely is.

I have a 2002 Chevy Impala, it starts great in the morning when the engine is cold, but once the engine warms up it is very difficult to start. It cranks alot and even backfires sometimes. Also I noticed...


Engine is difficult to start when cold
  1. Check the battery condition, battery state of charge and starter motor current draw. Replace the battery if marginal and the starter motor if the current draw is beyond specification.
  2. Check the battery cable condition. Clean the battery terminals and replace corroded or damaged cables.
  3. Check the fuel system for proper operation. A fuel pump with insufficient fuel pressure or clogged injectors should be replaced.
  4. Check the engine's tune-up status. Note the tune-up specifications and check for items such as severely worn spark plugs; adjust or replace as needed. On vehicles with manually adjusted valve clearances, check for tight valves and adjust to specification.
  5. Check for a failed coolant temperature sensor, and replace if out of specification.
  6. heck the operation of the engine management systems for fuel and ignition; repair or replace failed components as necessary.
Engine is difficult to start when hot
  1. Check the air filter and air intake system. Replace the air filter if it is dirty or contaminated. Check the fresh air intake system for restrictions or blockage.
  2. Check for loose or deteriorated engine grounds and clean, tighten or replace as needed.
  3. Check for needed maintenance. Inspect tune-up and service related items such as spark plugs and engine oil condition, and check the operation of the engine fuel and ignition management system.

2002 pathfinder killing the battery for no reason. Sometimes overnight others it takes a couple days. Replaced batt. and alt. but problem still exsists. Ive already checked each circut by pulling fuses for...


to check for a parasitic battery drain, you will need a multimeter. set it on the 300 mA setting then remove the negative battery cable on the vehicle. put the multimeter's negative lead on the battery post and the positive lead on the vehicle's negative cable. the meter will tell you how many amps are being drawn. usually, there's a temporary spike (a second or two) for the vehicle's security system, relays, etc. after that, you should only see a draw of approximately 30-40 mA, which is the digital clock, memory settings on the radio, etc. if you're seeing a larger draw, you can begin removing main fuses in the fuse box under the hood to see where the draw is coming from. it's also possible that you may have a bad diode in the alternator, which would cause the alternator to draw current away from the battery when the engine is not running.

02 ford focus battery dies over night having problems checking for a draw in the system any help


Disconnect the negative battery cable and put a test light between the cable end and the neg post. If there is a draw, the light will light. Remember the doors need to be closed and the underhood light disconnected (these are draws as well). If the light is lit there is a draw. Removing fuses until the light goes out can pinpoint the circuit. Finding the actual short can tougher.

My 2000 ford expedition has a shortage that keeps draining my battery


Disconnect the negative battery cable. Put an ammeter between the negative battery terminal and the disconnected cable. Remove fuses one at a time and look for a large drop in current. The fuse with the big drop is on the circuit with the short.

Note that even with the ignition off the radio, the alarm, and the remote entry will pull a few milliamps each. The control module might also draw some power.

After locating the circuit with the problem you need to check wiring and components for shorts.

A service manual (Haynes, Chilton, etc.) with a wiring diagram is helpful. Check your local auto parts store for manuals.

1996 sable has a sizable draw on the battery even when everything has been turned off, including the ignition. there is no trunk light or anything of that nature. any ideas?


disconnect the negative battery cable and install a test light -one end on the negative post and the other to the disconnected cable. if it glows brightly, you have a big drain. Have someone watch the light while you pull all fuses 1 by 1. When the test light goes out as a certain fuse is pulled -see what that fuse goes to and there is your problem.

Something is drawing power from the battery constantly


PUT A TEST LIGHT FROM THE GROUND POST OF YOUR BATTERY TO THE GROUND CABLE CLAMP.REMOVE THE CLAMP FROM THE BATTERY AND THE LIGHT WILL LIGHT IF THERE IS A DRAIN.START UNPLUGGING STUFF [START WITH THE ALTERNATOR] AND WHEN YOU GET TO THE DRAW THE LIGHT WILL GO OUT. TRY PULLING FUSES TO NARROW DOWN THE CIRCUT.WHEN THE LIGHT GOES OUT CHECK THE OWNERS MANUAL TO SEE ALL COMPONENTS THAT YOU NEED TO CHECK. MOST OF THE TIME THERE IS A DIODE GONE IN THE ALTERNATER CAUSEING A 4 AMP DRAIN,IT WILL NEED A RECTIFIER PUT IN IT.HOPE THIS HELPS.

2002 golf . replaced battery 18 mounths ago now


You need to check if some accessory is drawing power when the car is not running.
About any inexpensive digital multimeter will have a 10 Amp unswitched range. You would need to detach the negative (ground) cable from the battery and put the meter in series with the leads plugged into it to access that range. - Do NOT turn on anything while so connected! It will fry the meter. Normally, there will be a very small amount of current flowing even with everything 'off.' This is normal as there are things still 'on' even though the car isn't running; the ECU will draw a tiny bit, your radio will too and any kind of clock that keeps time will also draw some current.
If you find anything over 1 ampere, you have a problem which must be found as this will drain any normal battery over a two-day period.
One item may have a failed part and cause this; your alternator. It has semiconductor parts in it (normally 6) called diodes and if one has been slightly damaged, it can draw current from the battery with the engine off and not light the warning light on the dashboard.
Good luck-

Battery goes dead when car sits 3-5 days 98 park ave


Obvious that something is drawing down the battery...Put a test light between the negative cable and the negative post of the battery (remove cable first) start pulling fuses till light goes out. That will tell you what system is drawing...you can then begin looking for the actual problem. If all fuses pulled and light remains on ,chances are you have an internal alternator problem.
