92 Buick riviera
Heat is coming up form under dash. Had to shut
vents too. Tried to change temp. Settings!
Everything. It's hot driving my car. Help
Look at your first post.......I ask some questions that you have not answered. Your problem could be.... (1) lost vacumn to a/c controller (2) something has broken (3) the dash unit, where you change the setting is not responding because the contacts are contaminated.
Greetings..Please check the firewall beneath the dash for any holes..pay particular attention around the base of the steering column..to make sure the couplings are in place. Good Luck..SEMPER FI
