GM made a controller on cars with automatic air (were you set the temp and it holds there) When they fail you get the condition you have. Good used controllers are fairly easy to find in pick n pull....mostly on full size GM car up thru mid 1995+ Picture attach shows location on a Riviera. ...it is part #1
