My 99 Denali is having multiple electrical issues. I have the dash lights come intermittently, such as brake, 4x4, ABS, security, engine, etc. I have no radio, clock, power windows, locks, wipers, sound, etc. I pulled the center console off and found the BCM. On the part labeled with "D E F" there is a grey or maybe brown thicker wire coming from it. When I push down on it everything works again and all dash lights go away. I thought it had too much tension and that was problem but now after 2 days of driving everything went out again. Do you think the wire/s just moved again? What else could it be? It seems when I turn the steering wheel to the left the power will go out. If I touch the wipers at all or the windows the power will go out. I do hear clicking where the fuse box is by the driver side door. Can you help me figure out the colors of the wires and what each one does? A picture of the inside of the console would really help too, if you think I can match them up and see what looks different. Thanks for your help!
?€¢
The EBCM detects a low brake fluid condition and sends a class 2 message to the IPC.
?€¢
The IPC performs the bulb check.

An ABS-disabling malfunction also disables dynamic rear proportioning (DRP).
Whenever
this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS, TPMS and BCM faults and others) as long as the light is on. You
must now have the dealer hook up a special electronic diagnostic tool
and "scan" the system for the fault code that is stored for
the problem(s)

thank you! now im having trouble starting too...could this be the same cause?
black or brown is ground red is negative I believe, you can check the gmc website for colors; did you pull a fuse, cause some cars if you pull a fuse sometimes they are connected to the whole car and you would have to get it programmed again at the dealer , my friend had to do that trying to get the door chime to stop and everything went off like yours?

Sounds like your computer is messing up, get that checked cause it could cause more problems driving it...
