I had to replace my battery now the battery light came on in 2004 XJ8 a while ago. Rear turn signals, brake lights and heater fan stopped working. I disconnected the battery and reconnected it, things worked for a while but stopped after a week. Water got into the wheel well at some point before all this started happening I drained it and things just progressively get worse. I have searched the net high and low and cannot find a possible place to start or solution ....Any all help or suggestions would be greatly appreciated. New to this forum not sure how to retrieve answers from here

Just recently retired Electrical Inspector. Got a little time on my hands, My daughter purchased a 2004 XJ8 at an auction and decided she didn't want it so I bought it from her. Didn't realize so much work needed to be done to get it running but once I did, I fell in love with it,
Just recently water got into the wheel well and now the battery light stays on, rear signals and stop lights don't flash or light up . The parking assist beeper activates in Park when the garage door is closed and the climate control fan stopped working,,,,I'm at a loss here fellas. I've looked on line for manuals for this vehicle...no luck. Any thoughts about where and how to begin to fix this latest problems would sure be appreciated....The nearest jag mech is too far away and I usually like to tinker and do things myself.

Battery light will come on if the alternator is not charging. Did a wire get loosened somehow during the battery change?

Good to have you with us at Jaguar forums.

That sounds like the root cause of your electrical issues. You need to identify what got wet and the resulting damage. Sounds like the rear park module for a start.

I checked the battery connections. Sprayed and cleaned everything I saw with electrical contact cleaner. Disconnected the battery for a short while to reboot. The climate control fan came back on and so did the brake and turn signal lights for a about 5 days and then it started all over again. The battery light was still on but the cascade of events started with the fan stopped working and then rear signals,the brake lights and the parking assist rear beeper whenever anything in close proximity approached with any gear. Also noticed that the fan stopped blowing when the vehicle was placed in reverse gear.
