Re: Ac problem with my 1972 chevy truck
Sounds like maybe flapper door isn't closing or something. Hopefully someone will have more info on it.

The flapper door is located under the cowl on the passenger side just under the pass side wiper.

Re: Ac problem with my 1972 chevy truck
I agree with the Vac problem... however, these trucks won't defult to the defroster vents. Those doors and flappers are all manual on these.
