I own an 86 Brougham RWD. It has been snowing like a B*tch here the last couple days (southern NH). However the defroster in my car will not work. There is also no heat / anything coming out of the dash vents. Anyone know what could be causing this, its taking me forever to get my window de-iced before work every morning. Thanks.

A good place to start would be with the blower motor, if there is no air blowing out of any of the vents at all. The blower motor is right on the firewall next to the passenger side front fender. They only cost $25.00 at NAPA auto parts.

The heater control module (abot $120. fro carquest) seems to control everything.. from the blower to the temperature... just rreplaced mine. now it works.. but I wish there were a way to remove all the electronics and go with an old style heater switch.
