The dealership told my girlfriend that the radio was skipping because a "stuck seek button". I know that can't be the problem because it skips randomly when playing a CD. The check engine light went after changing out the O2 sensor and adding a new air filter. The spark plugs have since been changed and so-far so-good (knock on wood).
 
I think the problem with the radio lies in the steering wheel as it has controls on the back of the pillars. The buttons seem like they've been mashed beyond function and don't work when pressed.
 
As for the gauges, I would *GUESS* there is either an electrical short somewhere throughout the vehicle, or the ignition is bad. I would look for articles or posts on that problem elsewhere. Also, if you can find a Haynes' Manual for you Jeep, I would. I will as soon as I finish this post...Good Luck!

Nope, note yet. I know what you mean when you say you are ready to give it away. I would, but its so hard to when it runs so good. I just picked it up from the dealership yesterday with no leads from them. I did get some good leads from other forums. I have been told that my BCM must not be getting power. Being that it is new, it must note being getting power since it is not communicating.
 
I have been given a list of wires and areas to check that would most likely be the problem for the power outage. So as soon as it quites raining I will be digging in.
 
I will let you know if I fix it.

#45 of 707 2000 jeep is crazy by mustanggt_91

Aug 29, 2008 (8:59 pm)

I have a 200 jeep grand cherokee that has gone nuts. first the pcm went bad and we fixed that with no problem. but now everything is nuts. I can't communicate with bcm, windows don't work from any door, overhead console won't display numbers at all, a/c will not turn on, instrument cluster goes crazy every now and then, and sometimes vehicle dies as if you just turned it off. it always restarts but will eventually do it again. any ideas anyone.

#46 of 707 2001 Jeep Grand Cherokee Limited AC/defrost stalls engine by genekmah

I have traced the wiring harness with a fault finder from the condenser to the fuse block with no shorts detected. I have also replaced the TSP and crankshaft sensor. It mostly happens when it's hot outside (above 80). I can't get it to replicate all the time, but when it happens, I can consistently get it to die when I turn on the AC or defrost. Won't stall the engine with the blower on by itself. Changed the relays and checked fuses and it still stalls. I think it's narrowed down to the AC (automatic climate control) head unit or the PCM. Any ideas?

I have a 2002 Grand Cherokee that i bought new. It now has 108k miles on it and i have wanted to trade it off for something else but my wife likes the thing. I am tired of working on it! it all started with the power steering system that i pretty much replaced all parts, and then the window regulators. A couple of months ago the windows quit working. I thought maybe i did something when i put in the new regulator in the drivers door, but couldnt find anything. Then the AC quit working, the overhead computer quit working and the lights did funny things. I searched here online and found one posting where someone found a bad wire in the drivers door and tore back into it. Where the wires go through the rubber boot from the drivers door to the door jamb, i found THREE SPLICED WIRES!!! This vehicle has only been worked on or serviced by myself and i know i have never pulled back the rubber boot. The wiring harness must have been spliced from the factory! I soldered in about two inches of new wire and heat shrinked the splices, unhooked the battery to reset the computer, and IT WORKED!!!! I could have spent thousands on diagnostics in a shop and they may never have found the problem!!! I suppose it just took a dumb farmer to find a problem that was built into the vehicle at the factory. This is our second Grand Cherokee and i can honestly say there will not be a third. Good luck

That is weird. I noticed several factory spliced wires in the door and under the dash. But they looked like they were still tight though. But that may not be the case, they could be loose I guess. I will take those wires and add new wire to it.
 
Thanks for the tip, maybe this will help.
 
Oh yeah, and I hate jeeps now. I do love the 318 V-8 thats in it, so much power and wont get stuck anywhere. But I have had two jeeps now with these strange electrical problems. Sad to say, but I am done with Jeeps after this.

#49 of 707 Thanks to y'all (05 GC electrical) by smithed

Thanks to all for the input above:
 
All the panel warning lights were intermittently lighting up for a few seconds, then going back off. Thanks to what I've read here, it was easily fixed by cleaning the battery posts and cable terminals and tightening them down well. (2005 Grand Cherokee 3.7L)

#50 of 707 2005 grand cherokee cuts off during turns by gulfgirl

Sep 16, 2008 (6:16 pm)

In the last few weeks I have had several incidents of my jeep just turning off when I am in the middle of a turn. I have to put it in neutral, then turn the ignition and it just starts right back up. It has only done this while I am in the act of turning. Luckily it has only occurred when I have been slowing down - like turning into the garage or pulling into a drive thru lane. This issue started right after I had the dealership change out the battery (since I couldn't find the battery at any of the local part stores). Could it be possible that something happened during the battery installation that would cause this or is it just coincidence?
