I have a '97 Z28 6 speed that I recently purchased. The cruise control is not working, nor is the AC. The AC compressor is not kicking on at all. Supposedly the AC system was gone through and a new compressor installed a few months before I bought the car.

The 15 amp fuse under the hood for AC and cruise is good. I also checked third brake light (in the spoiler) is good, which I know is a common cause for the cruise not working. Anyone have any ideas where to look next?

edit: Forgot to mention all other brake lights are good. Also just cleaned the 3 easy to access under-hood grounds (the two along the rad support and the one near the battery.) For the cruise, I haven't checked the clutch pedal switch yet, so I'll do that next. Not sure what to try next for the AC though.

Cruise control) When you look at the throttle body, are there two cables hooked up? One should be for the throttle, the other should be for the cruise control:

For what its worth, here is where the cruise control module is located:

AC) I would check your vacuum lines and your HVAC check valve for cracks/leaks. Also make sure that your AC pressure sensor is connected.
