Curse control wont set just stopped working, changed fuse still nothing.

Look for fuse blown. Maybe marked crtsy on old GM cars it was called courtesy, on other cars it's marked CIG. If you have an owner's manual, find out which fuse operates all three of those

C5 radio doesn't need a code - if it's not turning on, I would start with check for blown fuse.

I would check all fuses to see if any have blown.

Access the ABS Module & check the codes

Diagnose the system & component test, to find
the problem with Trac Control

there is two sets of fuses on this car i think. The centre console lights are on fuses inside the car under the dash, is your interior light not working either?

Sounds like the problem is on the steering as the set button works from the same module as the resume and cancel

check fuse

its not a fuse i had the same problem on my 03 x5 it an ac resistor thats at fault it controls your fan once it goes your fan wont come on or comes on intermitently once again the faulty part is a blower motor resistor should be 100 bucs at dealer or if you shop around i got mine for 75 from local parts store (carquest)

there is a resistor located under the dash which controls the settings for the fan if this has overloaded or blown up the blower motor wont work

it's normal, windshield wipers in bmws are connected to the speedometer since the old E36 3series, so they stop whenever you stop your car. If they start again once the car moves there's nothing wrong with your car!
