Question about 1997 Jeep Grand Cherokee
This can be a possible issue with the part commonly called the BCM or Body Control Module. The operation of the locks is you guessed it computer controlled. I suggest you see the dealer and have the BCM scanned with a special tool to see what is going on.

Not to insult your intelligence or anything, but I had the same problem, and fixed it by replacing fuse #13. It was caused by a short in my cigarrette lighter. Good Luck!

car electrics are a nightmare. the car lights up when a door is open i presume. and by bypassing the central locking. the electric computer says there is a fault. and will not start. that i think is programed in. best thing to do is. go to phone VW dealer ask about diagnostic test without repair. about £35 then fix it yourself. they garentee it right I think. the dealers have come into line better with that kind of thing phone and ask anyway.

if you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
check outputs from module pin 3 & 4
that go to door locks

very common problem is the door lock actuator. i would recommend replace that. a good idea also would be to remove the door panel and check all the rods that connect to the assembly and make sure one didnt pop off.
