My friend had the same problem with his sc400. Says it's usually
a relay located not too far away from your left foot when your
driving. Sry about not being too specific but it should be a good
place to start..
I had this happen in my SC300. Check your fuses including A/C
AND cigarette lighter fuse.

Asked in Buick Regal, Ford Expedition XLT, Car Heaters
What is wrong with the heater controls on a 91 Buick Regal when the heater controls wont switch to defrost vent etc even when the lights on the buttons iluminate?
Many of these controls are Vacuum operated. You may have a
problem where the "Main" Vacuum line has broken. See if you can
locate this line by using your manual and make sure that it is
intact. TommyTrouble

Had same problem. Is your temp gauge reading normal? If temp
gauge is reading low after driving awhile, may be the thermostat
stuck open. If so, easier fix than heater coil.
