Help! when turn on car, heat is at full blast cant turn... - 7/4/2008 11:29:18 AM    colepops   Posts: 4 Joined: 7/4/2008 Status: offline I have a 93 deville and when you start up the car, the heat is at full blast and there is no power to the heat controls to shut it off.  The gas gauge also does not work now.  All the fuses are good and so I dont know if its an electrical problem or something else.  Help!  Post #: 1
