: a/c control modual

03-26-06, 09:20 PM
Hey Folks
I replaced my burned up looking a/c control modual with another used one form the junk yard. Now the fan works, but blows only at the floor. I also know that the a/c system has no freon. The people I bought it from opened the system to replace the head gaskets. ( This is a 1987 Brougham 307)
My question is..........Does the system have to have freon in it to make the blower send air thru the dash and defrost vents? OR is all air flow vacuum controlled?

No it doesn't need the refrigeration working in order to direct air to the defrost or dash vents.

Thanks Ape Man.
Do you think it sounds like a vacuum problem?
