Hi all. I'm in the uk and found this site and am hoping this wil help me solve a year of grief and hassle as I just can't seem to get to the bottom of the mess!
Jeep grand Cherokee on 2004/05
At the start I was getting problems with the interior lighting. The lights on the cockpit were dim and I had to turn the light switch to full on the stick to get it to brighten up. But that meant having all interior lights on.
So I took the car to the local garage, he found a broken wire in the drivers door, he repaired the wire which then solved the problem.
However since then I have had no central locking and can only operate it from the drivers door button when getting out, and just using the key to unlock the drivers door getting in.
The chap said it needed re programming as the wires had been disconnected. So I took to a garage recommended by the main dealer as they don't do servicing.
They plugged in and the computer is receiving the signal of the key fobs and they re programmed it and it still doesn't work.
They say they can't tell me what the problem is without taking the car and investigating which I thinks bull! £££££££
I have googled a few bits and some people say maybe its the imobiliza antenna?
Not sure if its related but ever since I've had the car one of the remotes has been temperamental but the other was fine, however they both got tested and they say they are both sending signals and the Ecu is reading it. But just not locking or unlocking the car
Also I must add it all works when using the button on the drivers door.
The report from the garage says this
Try to programme CID for keys
Programme both fobs and works through drb inop on car.
I'm at a loss and the only option I have is to have an aftermarket central locking system fitted which will lock and unlock doors from new key fobs. Not sure it will still activate alarm etc though. I don't realy want to do that as I would rather keep it all original.
If I can't fix it I'm going to have to sell it as my wife is struggling with the locking etc with having to baby's in back its a right Pain in the arse as one she gets the kids out she needs to go back to drivers door and open it and press button to lock it. Also has to unlock drivers door then open door and press button on door just to unlock all doors.
Any suggestions would be so great full as I realy don't want to sell it but she's lost patience!
