1998 Jeep Laredo continuous clicking sound passenger side under dash it runs battery down ignition is off continuous clicking please help thank you


A number of people in the link report the same problem on the Jeep Forum and there are a number of fixes.

I also found this for you.

The problem seems to be a short in one of the rear dome lights, which seems to be affecting two fuse circuits. The temporary solution was to remove one fuse and replace another (blown), and remove the bulb from the bad dome light. I had to remove "fuze#5-15 amps-Interior Lighting", this stopped the clicking noise, I replaced blown fuze#8-15 amp-Overhead Console, keyless Entry ..." This fuse also seems to effect the alarm system (contrary to the documentation), and I think that was what was killing the engine. The problem existed before fuse#8 blew. Removing fuse#5 may have solved the problem, but the other fuse blew while I was testing the dome lights, and the jeep will not start without it.

Found lots of wires bare or broken in all the door wiring harnesses ( in rubber boot that goes to the door)I first checked both fuse 5 and 8 but both o.k. After fixing the broken wires found fuse 8 had blown. Replaced that and all is well again. Thanks for the advise got me looking in the right direction.

. Fuse box located in passenger side door jam...check #8 fuse if its not blown check others...if it is blown, check your radio, and interior lights for good ground
Clicking noise under passenger dash Jeep just shuts down

Interiour light dosent work *** lighter dosent work


First thing to check: fuse(s) for the cigarette lighter/power port, which may also be the same fuse for the interior lighting that went out. Could post the location of your fuse box (most Hyundai cars have 2 - one under hood, and a second under the dash (where your power port/interior lighting fuses are most likely located)), if you could clarify which model/year/engine size Hyundai car/truck is giving you problems.

Need help with blown fuses in mazda rx8 2004. Husband removed the messed up sunvisor and now the radio doesn't work or the display and the map lights and keyless entry/alarm aren't working either. Car...


2003 MPV. Room Fuse would immediately blow when replaced - as a result, no audio, auto doors, interior lights, etc. It would blow without the key in the ignition so I knew it had to be something that operated without the electric being turned on. Started guessing by pulling the fuses for the auto doors then retrying the Room Fuse.. Room Fuse continued to blow. Then went through interior lighting - started taking out bulbs and disconnecting lighting connections trying to isolate the issue.. popped the visor mirrors out and noticed one of the connections had come loose.. reconnected, popped in another Room Fuse, and presto! Everything back to normal - lucky me.

2002 pt cruser has electrical problem no keyless remote entry, door locks don't work, no interer lights,no radio. insterment panel says "no fuse" check engine light on.


I recently had the original battery on my 2003 PT Cruiser GT finally go bad and I replaced it. In the process of it dying (and me having to jump it a couple times before I could get to the store to buy a new one), I lost my interior lights, the memory on the trip odometer, my power locks, my remote key fob capability, my radio/CD player, and the odometer display showed a "NO FUSE" message alternating with the overall mileage reading. http://www.ptcruiserlinks.com/forum/images/smilies/frown.gifThe car still ran fine, but it was obvious I had blown a fuse or fuses.

I did some checking online to see if anyone had experienced this set of outages before (and the "NO FUSE" message) and there were several references to the IOD fuse, but no clear definitive answer on a) what it truly affected and b) how to replace it (since it's in a protective clip you pull up). Since I just did that and everything is restored, thought I'd share the info for those who might lose power to the above items and keep them from wasting a lot of money at the dealer for a simple repair. Here's the scoop:

1) I bought a fuse tester/puller at a local auto parts store, which enabled me to individually pull all the fuses that were labled as having anything to do with the interior lights, radio, or locks. This included those in the fuse box by the driver's left knee inside the car and a 40 amp fuse up in the power distribution box under the hood. All checked out good, so I strongly suspected the IOD was the culprit.

2) I never did find anything in the manual or online that said exactly what that fuse affects, other than it is used during initial transport from the factory to dealers to minimize the drain on the battery by pulling it up. To reiterate what I mentioned at the beginning of this book, I know it affects at least the following systems:

- Interior dome/reading lights (the dash lights, head- and tail-lights still work)
- Power locks (both the door switches and the remote fob capability)
- Radio/CD/Cassette player (though the unit will still show trim lighting)
- The trip odometer memory (which would reset each time the car was shut down)

3) I crossed my fingers that the IOD fuse was the cause, as I really didn't want to take it to the shop and pay big bucks. The yellow 20-amp IOD fuse is in the fuse box (power distribution center) under the hood and just behind the air filter housing. It stands out because it is encased in a protective clip that allows you to pull it up to break the circuit, but leave it in place for transport and not get lost. The challenge is getting it out of that clip. To make it a bit easier to access, I removed the housing top to the air filter, which is simple (disengage the clips on the left side and the right front side, and then the screw holding the retaining ring on the rubber hose on the back left side).

4) I found that taking a very small, thin screwdriver that I use for glasses screws worked well. You'll see a small rectangle opening in the top (where you'll be able to read the "20" on the fuse). I think a small curved tip screwdriver would work, too. Take the tip of your screwdriver and insert it in the opening, with the pressure up under the left side of the opening (the top is actually hinged, with the left side being where it clips down in place and the plastic hinges on the right). It takes a little effort, and I used my left hand to try and help unclip the left side of the clip while I applied the out/lifting pressure with the screwdriver. After a while I got it, and the top opened up to allow access to the fuse.

5) Took out the fuse, tested it--sure enough, it was bad. Popped in a new yellow 20 amp mini fuse, closed the top of the clip, reinserted the fuse into the fuse box by gently pushing down, and then checked things in the car. Voila! I had everything restored. http://www.ptcruiserlinks.com/forum/images/smilies/1st.gifYeah, baby! That was probably $100+ saved and it only cost me some time and one little fuse.

I know this was long, but hopefully it will help someone who is trying to figure out what the heck is going on with their electrical stuff. I suspect this probably happens fairly often to folks and they just end up bringing the car in, especially when they've check all the other fuses properly labled for those accessories. Thanks much, and now it's time to get back to cruisin' in my PT GT!

My 1996 dodge neon wouldn't start...mechanic told me it was the battery...replaced battery still after sitting for too long won't start took it to another mechanc...not the alternator. he said that a wire...


try and check for small lighting...under hood light, trunk light...maybe those turn off buttons could be stuck in. Or, maybe you have map lights under the rear view mirror on?

Same problem with an '03 Golf--remote entry, power windows, and interior lights stopped working. This was easily fixed by replacing fuse #14, (10 amp), located in the driver's side fuse block.

Fuse or what


Your multifunction switch on the steering column controls your exterior lights. The GEM module controls the interior lights and other stuff. If bad, it would not blow fuses. WHich fuse blows?
Your Ford dealer might be familiar with this issue, so call the service dept and ask them and get a quote. It may be wiring.
reoprt back.

  • The high beams are inoperative
  • Circuitry.
  • Multifunction switch.
  • Go To Pinpoint Test C .


--------------------------------------------------------------
Principles of Operation
Generic Electronic Module (GEM) The generic electronic module (GEM) receives inputs from the following:
  • door ajar switches
  • liftgate ajar switch (wagon)
  • liftgate glass switch (wagon)
  • headlamp switch
  • keyless entry keypad switches
  • the powertrain control module (PCM) (vehicle speed signal)
  • ignition switch
  • remote keyless entry transmitter
The GEM uses these inputs to control the output to the battery saver relay and interior lamp relay. Both relays are integral to the central junction box (CJB) and cannot be accessed directly.
Interior Lighting Systems The GEM grounds the battery saver relay and interior lamp relay coils when any door ajar switch or the headlamp switch is closed. The interior lamp relay then supplies power to the interior lamp circuit. Vehicle speed must be less than 15 kph (9 mph) for the GEM to ground the interior lamp relay. The interior lamps will remain illuminated for a period of up to 25 seconds after all doors are closed or until the ignition is switched from the OFF position, or the GEM receives a vehicle speed signal. Actuating the interior lights from the headlamp switch will operate at any time.
Illuminated Entry Illuminated entry is activated when a keyless entry keypad switch provides ground on the GEM input or when the GEM receives an unlock signal from the remote keyless entry key fob. The GEM then provides ground to the battery saver and interior lamp relay coils. Illuminated entry is deactivated when the GEM receives a lock signal from the remote keyless entry key fob or if the GEM receives ground inputs from the keyless entry keypad switch lock code. Illuminated entry will also be deactivated when the GEM receives input voltage from the ignition switch.
Battery Saver The battery saver is activated when the GEM is not receiving voltage input from the ignition switch (off position). The GEM will then provide ground to the battery saver relay coil for a maximum of 30 minutes depending on the state of the interior lamp switch inputs to the GEM. The energized battery saver relay switches voltage to the demand lamp circuit and the interior lamp relay coil. After time-out, the GEM removes ground to the battery saver relay disabling the demand lamp circuit.
Puddle Lamps The puddle lamp relay operates reverse from the battery saver relay and the interior lamp relay. The puddle lamp relay coil receives voltage when the ignition switch is in the START or RUN position, which disables the circuit to the puddle lamps.
Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.
