My cruise control is inoperable, where should I start looking after I verify that the fuse isn't blown?

 

not sure on the f-body's, but I have seen a burned out CHMBL (center brake light) kill cruise in other GM cars.

 

looks like all you need is lots ok luck...so good luck

 

This is a pretty widespread and common problem in these cars. Some have found that the 3rd brake light will go out and cause the cruise control to stop functioning. I replace my tail lights and it still doesn't work. I've heard of people replacing the entire cruise module and it still doesn't work, so basically, good luck, since there's no concrete solution.

 

On mine the brake pedal switch had moved. Easy fix.
