Hi guys,
I'm having some electrical trouble with my '98 XJ.
I've just rewired both doors to repair some broken wires in the door jamb. When finished, I tested every wire for continuity then reassembled.
Everything is working 100% (power windows, power mirrors, door lock, speakers), except I'm now noticing that every time the dome lights come on (by opening door or twisting headlight switch) or I roll a window up/down, the radio switches off.
I assumed that it must be something to do with my wiring, so I disconnected all the wiring from the front doors. Even with all the front door wiring disconnected it's exactly the same! I open a door (which turns on the lights) and the radio turns off. If I press the door jamb switch back in the radio comes back on!
I'm really starting to feel like I'm at a loss. I can't see any other loose connectors, and this is definitely a new problem.
Any ideas where to start?
Thank in advance!
Edit: I should add, the radio is still getting power when this happens. It's acting like it's shutting off for safety, so I'm guessing 12v is getting somewhere it shouldn't.
