Brakes problem
2002 GMC Sierra V8 Four Wheel Drive Automatic

I replaced the brake light switch but now the truck won't come out of park when I start it. What did I do wrong?

Check the brake switch adjustment/other adjustment that's on the brake switch assy- its tied into the shift interlock system/CC, the shift lock is not being activated that's causing your problem.
