=== Electrical problem
:D I just bought a Jeep Grand Cherokee 05 Limited, that was involved on an accident, I sent to repair shop and and after repaire, found that some electrical systems do not work, I just took a look down my steering wheel and I saw some cables cut, I reconnect them, and now the AC is working but the following system do not work:
Interior lights
Mirror Control
Memory For Radio, Driver Seat, Mirrors
Car Alarm the light flashing( I can lock and unlock the car)

I already check all relays and fuses and they are OK!
Any clue?:confused:
There must be something that all these systems share are connected to !

Hector PTR :thumbsup:

Re: === Electrical problem
IIRC all those are connected to the FCM Front Control Module ... check out to see what is controlled by what ... and if you already found cut wires I would follow the wires and see where else it was cut

Re: === Electrical problem
The FCM is in the front drivers side in the engine bay it's infront of the fuse box most closest to the head lamp ... best thing to try at this point would be have the dealer flash that PCM and everything else see if it helps ... if not then like I said try following some of the wires it maybe a cluster but well worth it

I had some electrical problems mine turned out to be some contacts that needed to be cleaned ... try that too ... there is a harness behind the fuse boxes, unplug that big harness use some di electric cleaner and let it sit unplugged over night with the battery disconnected also the same for the PCM

then we can take it from there
