Replying to: tuggajb (Jun 13, 2008 1:29 pm) . Does not Work 1. Windows 2. Automatic head light sensor 3. Door locks 4. Temperature Display (not eng) outside temp 5. Map lights stay on (if setting is on auto) 6. Air Conditioner compressor does not turn on 7. All gauges do not work ( work briefly if i press on the brake) I sent my Jeep to a mechanic I had problems my gauges did not work and he said it could be a coil spring or ignition. He serviced my vehicle and changed the ignition. That did not fix the problem but the items listed above do not work. He did a diagnostic check and the computer would not respond. He said my accessory control was most likely bad. He checked the coil spring and said it was good. He said most likely I should take it to the DEALER. Symptoms I would press on the brake my gauges would work briefly. If I would put my turn signal my gauges would work briefly. If I turned my wipers my gauges would work briefly. My windows would roll down if I would stop and turn off my ignition. Now they just don’t work I would be driving and my turn signal warning chime would go off. The jeep has stalled three times but started back up. All the vital stuff works such as Turn signals Head lights I have not had any problems with the transmission or engine it works just fine. Except when it stalled those few times. I can hear a clicking noise under the dash it sounds like a relay clicking. I since have sent it to the dealer (bunch of yahoo's) they have never seen the problem. RIGHT! look on the internet I am not the only one. They diagnosed the problem as the instrument cluster. I tore into the dash this weekend and looked for all the posted possablites and I found no corrosion no spliced wires in the boot of the door. I did find a burned connector for the ac as soon as I touched it was Hot and then the blower turned on. This part is called a Resistor for the blower fan. (OEM INSTALLED RESISTOR SYSTEM FLOW SENSOR (DELCO MODEL #16250779, SERIAL #0304021) I went to the dealer got a quote for the part and casualy asked him if he had a lot of call for this part he said yes. I asked if there was a recall on it he directed to the service deptartment and there is no recall. Funny thing is that they also sell the connector to replace the melted male adaptor. I just want to know if anyone has checked this sensor its located under the passenger dash next to the blower. I just wonder since this Fried under the dash if this has caused some sort of ground or actually fried the computer and I wonder why It did not blow the fuse...Its unplugged for now until I replace it. Since I have disconnected it has not helped the guage issue. I now notice that the window control on the door makes a clicking noise and turns on and off from door to door I am just wonder if this could be a multiude of problems. I used to love my jeep. As the saying goes if you love them you must let them go..

| I have a 2006 Jeep Grand Cherokee that I bought from a dealer. It has about 45000 miles on it. Runs great. For about the past 4 months, the Brake Trouble light has been blinking every once in a while. This is a brake trouble light and the emergency brake light combined into one. It only does it when I use my brakes or when I hit a bump on the road. I tried to get a DTC code from the computer and nothing shows up in the freeze frame memory. I took it to the dealer and they could not find an issue with the vehicle considering the light wouldn't come on when I took it in(of course). I was wondering if anyone knew where the brake sensors for the brake system are located and what they do and if anyone has any pointers on pinpointing the problem. | |

I have a 2002 Grand Cherokee. As I'm driving, I seem to get an sudden electrical short, where the radio shuts off, I hear the door locks click and the dash board display turns off, then within seconds it call comes back on. The car itself doesn't shut off and I don't seem to loose the headlights. It is sporadic. A mechanic looked at it, said that the alternator seemed to be fine, and he cleaned and tightened the battery terminals which needed it, but he said he couldn't find anything else. His thought was that there might be a short in a wire, which wasn't something he could find. Anyone have any other possible suggestions? Or does that sound the most logical and is it a dealer fix?
