1981 heater blower problem
MY 81 vette blows some air out of the dash, but not nearly enough. The blower is working on all speeds. It seems like something is impedeing the air flow. HELP

How does it blow out the defroster vents or the floor vent? I have an 81and there's plenty of air from the fan.

I would check my air ducts behind the dash. A lot of air can be lost thrue those ducts if the're not attached properly.

agree with RAWJ, probably loose fitting of ductwork, hopefully that's it, no cost just a bit of adjusting, let us know what you find.

Lots of ways to get debris clogging the system. An archives search should turn up all sorts of info on HVAC repairs and improvements.
