Help! Electrical gremlins driving me nuts!

[Rafa]

Hello guys!
I love my '02 X5, 130k miles and I need help from the Xoutpost gurus to help me troubleshoot my baby, I think it is a short because it happens intermittently, here are the symptoms:

It’s either the entire list below or none:
1. Seat Belt light on
2. No Steering Wheel controls (none)
3. No Wipers (front or rear)
4. No Horn
5. No lights on the vanity mirrors
6. The buttons where the heated seats and DSC cancel are not working
7. Tail Brake lights (sides and center) stay on all the time when the switch is on position 3.
8. Radio works independently from the car, it stays on after I shut off the engine but, stays on 25 min while driving and then shuts down, does not let me access the computer settings, not even set the time on the clock.

I have checked all the fuses and they are ok. I am thinking on two possible solutions:

1. Change the battery, there is no trouble at all when starting the car, not even in cold days but the guys from autozone checked it and the tester said bad battery plus the LED in the battery is not lit. ( I don’t know how old the battery is though)

2. Change the ignition switch, but I think it may not be it because the airbag light is not lit and when opening the mirror in the passenger side visor nothing happens (no steering wheel movement, nothing)


Last month during a heavy rain my interior lights were suddenly turned on and started dimming, the DSC, BRAKE and ABS lights also came on at the same time, along wiht the trans fail safe prog. Before that day everything worked fine.

Please share your thought with me, I try to ignore it but I can't it's just really annoying
