I have a 93 Cavalier that the cruise control quit working & the climate control won't change selections. No matter where I move the selector, it stays on Norm A/C mode. This happened occasionally before, and I always knew when the cruise would'nt work because the air would only blow out the vents. Now it doesn't work at all. Any suggestions?

Thanks

 

As with your cruise control, check if there's any busted vacuum hose. Inspect the vacuum lines and test other mechanical parts that are related to the CC for trouble shooting purposes.
