#25 of 34 Timer Switch/Electric Problems by jeepersheepers

Nov 05, 2011 (1:02 pm)

So I bought my '98 Grand Cherokee Limited about a year or so ago and the alarm system kept going off so I couldnt start my car, I found out how to get rid of that by cutting the purple and yellow wire but now I have to hook and unhook my battery up everytime I want to drive or I leave the car for too long because the battery will die. My dad thinks it's the timer switch and Ive tried two different ones so far but neither worked, anybody know what the problem might be? HELPPPP

I was in Indonesia, I have a 1998 Grand Cherokee 4.0, the alarm always goes off and the engine will not turn on. I've tried to lock and unlock using the usual keys and remote key, but failed to stop the alarm. I read a suggestion from the forum to grounding purple / yellow wire.
After opening the driver door panel, I do not find the purple / yellow wire. I think it's possible for Asia to have different wire colors. Please help me to explain exactly which wire to ground.

I had problems with the security system with my 2001 Jeep . I can give you the benifit of my experience . I had to take the jeep to the dealership . I had to replace the PCM . I had some things start working that had never worked quite right before. I purchased the module from a place in Miami Fla. for less than 200 dollars. I could have installed it my self . The PCM is located in the passenger side of the fire wall. Once you remove the cover and screws the PCM just plugs in. It was programed before they mailed it to me . You need to give them your veihicle number so they can program. cliick on this site to order a new one currently on sale but you can always find them for 199.00

Will this work on 94 GC ltd? My alarm can only be deactivated using the key on the passenger door. I recently had a squirrel chew some wiring but that has been repaired, but the car turns over but will not start. I think it might be the security system causing the problem, any ideas?
