I cannot direct the heat to the defroster, or the floor, or the dash, etc. The heater and temperature control work great...just can't direct the heat where it's needed. It's currently putting out a little heat in all directions...a little to the defrosters, a little to the floor, a little to the dash, etc. Any suggestions?I have a '98 Buick Regal LS and the heater control is not functioning properly.?
your vacuum line that directs the heat where you want it is leaking. you need to get it looked at and replaced and then all will be right with your heat.I have a '98 Buick Regal LS and the heater control is not functioning properly.?
it sounds like you have a electric mode door problem. the door could be stuck, or the motor for the mode door could be bad.you need to perform some diagnostic tests visually and electrically.
The ducts are usually cable operated or vacuum operated. I'm not sure about your car. It may be as simple as a vacuum hose falling off on the engine or under the dash. If it has a cable it might have jammed up. Either way I'd bring it to a mech.
