Hi back again! The problem still is going. I took the Jeep to a dealership. First I spent 338.00 and drove the Jeep 10 miles. It quit working. The engine will start then die. So this is what I'm being told. I replaced the BCM with one from a wrecking yard. New wasn't available. The dealership says that the BCM that we put in is shutting down the PCM and the only way to clear the problem is to buy new BCM and PCM and have them installed. I have all ready put 1100.00 into the Jeep. Now with the new amount with tax it will be up to 2700.00. I am at a loss. Why can't they clear the PCM and the BCM and start over? Program them to my car? Why do I have to buy new ones? Please someone technical HELP!!

My 05 GC 3.7 had numerous electrical probs. Horn wouldnt stop honking/clock spring fix. Lights flashing/ head light control switch fix. PCM issues/ bought preprogrammed PCM but took it to the dealership for a re flash because my TCM was not online. Replaced shifting module. I would never put after market products on this jeep. Stick to OE ONLY. I had fancy spark plugs put in even though AZ Auto parts told me it would be ok. To find out these plugs draw to much power to the packs. Use only copper core plugs. Please double check what fluids to use in your Jeep. Power steering and coolant are different. Its safer to use what the Daimer calls for in your Jeep instead of advice from back yard techs. Another good investment is a code reader/eraser that you can buy for a little over 50bucks seeing how Jeep likes to throw codes in your face. I would honestly say I would NEVER buy another Jeep again. By the time I pay off this Jeep I could prob work in the service department at the Jeep dealership.
#496 of 735 are radio and remote door lock issues related?
Jun 25, 2011 (8:20 am)
I have owned this Jeep for over two years and been very happy with it. I purchased it used; it's a 1999 GC with a 6 cylinder. The previous owner had installed an aftermarket stereo, and I have since installed a new Sony unit. My issue is this: The front door speakers would intermittently not work and now don't work at all. The remote door lock would ALSO intermittently work to unlock, but always lock. Now the remote does not work to unlock at all. BOTH of these events seemed to happen concurrently. I'm wondering if the passenger control module could be the source of my problem as the two seem to be part of both systems (at least according to what I read in the manual). I would appreciate anyone's input as far as a resolution for the issue is concerned. Thanks in advance!

Well, let me be the first to say this will continue. I purchased a 2006 Jeep Cherokee in 06 with 12,000 miles one it, and 2 months after having in it was in the shop every other month. Car wouldn't start, engine light comes on, lights flicker, the dash lights go crazy, and my car locks on all gears and won't accelerate after stopping at a stop light. The dealer couldn't find the problem while it was under warrantee, so they reset the intire conputer system they claimed. No problems for about 2 years and now the problems have returned. But, they discovered it now. Says I need to replace the computer that runs the car and it will cost some where around 1000.00. So, prepare yourself But another Jeep again, I will never. I love them but I can't deal will these issues. Everyone I know that has or has owned a Jeep told me to prepare for electrical problems. I didn't listen.
#498 of 735 TRANSMISSION SERVICE
Jul 01, 2011 (7:04 am)
I have a question for anyone, I had my transmission service about 3 months ago. and every since i've had nothing but electrical problem and it's pertaining the transmission. My mechanic hooked up some machine to my car, and the results were that it's was a default in the computer system that controlled the transmission. sometime my car won't shift gears, while driving the dash lights fro DNRP all lights up at the same time and i have to put the car in Neutral then back in drive in order for me to accelerate, the engine light won't go off and my head lights flicker of and on. Has anyone else had this issue after a transmission service?

Not sure if yours is the same problem. Our jeep was having crazy electrical issues the biggest on was cutting off while driving and at stops- very scary- we would have to put the jeep in neutral and restart. Our electric gas meter also did crazy stuff the speedometer went nuts and i think that was it. This went on for months and months taking the cars to many shops and lots of money.
In the end we finally solved the issue. It was the pcm- power control module- basically that is the computer system of the jeep. It cost us about 900 parts and labor, but the jeep runs great now.
Hope all of u figure out your jeep situations and maybe ours will help someone along the way. Honestly this is the first and last jeep we will ever buy- they seem to have lots of electrical issues. Good luck!

Hello, my jeep is nuts, my engine like turns on every other day, the head lights flicker off and on, then all light on the dash flicker and the gears DNRP all light up the same time and the car won't shift gears. I have to coast over and put in N or P the back in drive. Sometimes it won't start all, its just clicks and 5 or 6 tries it starts. No one seems to know what's going on, but I was told that I needed a new computer. That is was a default. But otherwise the mechanic says the transmission and engine was fine.
