Cruise control

[Corey Deming]

My cruise control doesn't work all my lights are good so that's not the problem what could be my issue

Check for a blown fuse (if you don't have the owner's manual you can find a fuse block diagram online)

Faulty brake switch

Wiring in steering column

I am not sure what you meant by all my lights are good. But one thing that can cause problems with these models are aftermarket LED lights. Don't know if you might have installed some LED lights or not .

Good Luck

Probably bad brake light switch. Brakes can be fine, brake lights can be fine, but the brake light switch can still prevent the cruise control from engaging. Happened to me twice. Buy the GM replacement part.
