2002 Trailblazer...been a GREAT car! But cruise control began not working intermittently. Then quit completely. We replaced the brake pedal sensor, then the switch itself. Also the related fusees. Didn't work. Took it to our mechanic who replaced the cam sensor (readout was showing an error). That did not work either.

Thoughts?

Thanks!

My cruise control stopped working when I got an error message also. I think maybe its the vehicles way of letting you know that something is wrong even though you cant tell.
When I erased the error codes with my code reader the cruise worked just fine until the error popped up again.
