I have a 1993 (40th Anniversary Edition) Corvette Coupe.  This morning, when I went to adjust the temperature in my air conditioning down a bit, when I depressed the "down arrow," absolutely nothing happened.  When I depressed the "up arrow," the temperature increased in single digit increments like it is supposed to.  Unfortunately, while messing with it, I now have my temperature set at maximum, which is 90 degrees.  Not good this time of the year!  Has anyone experienced this problem?  Any thoughts on how to rectify the situation.  Thanks!

On my 1988 I had an issue where I could not get my cool button to work I sent the unit out at a cost of 100 dollars and the company fixed the issue.  There are many videos on how to clean the contacts.  Take care and stay safe.

Bottom line:  You have to remove the HVAC head control unit, disassemble, and clean the button contacts which are located on a circuit board.
First video shows how to do it, second shows a more direct route for removing the HVAC head control unit.

Good luck!
