2003 Sierra Service 4WD and Service Brake System

Postby rt646 [OP] » Apr 20 2012, 8:36pm

I got in my truck after work the other day and had all sorts of things light up.

ABS and Brake lights are on.
Service 4WD and Service Brake System messages.
Radio on but no sound.
4WD selector switch does not work and showing in Neutral. (But it is not in neutral)
The display for P N D etc...is blank.
Shifts hard between 1 and 2.

Wondering if anyone else has had this problem before?

Any recent electrical add ons with this vehicle? First thing I would do is make sure your battery cables are tight. Intermittent electrical connections in this area cause all kinds of problems and it is a cheap fix.
