Factory Air??

4 Attachment(s)

So I picked up another Squarebody (I think I have a problem) This makes 3.
Probably just going to flip this one.

New balancer, alternator and a battery and it fired right up. This one has a 6 cylinder with A/C.
I never saw an HVAC control panel like this one. It has a vacuum actuated shut off valve for the heater core.

Re: Factory Air??

That is definitely not factory air. Factory air has the evaporator core mounted on the engine side of the firewall. It would look like this:

Re: Factory Air??

I was thinking maybe it was dealer installed. It has factory style vents in the dash too.

I forgot to mention that it works great. Blows ice cold.

Re: Factory Air??

it blows cold because it restricts hot coolant flow across the interior heater core...

Re: Factory Air??

That's not factory. There have been a lot of aftermarket AC systems that came and went... This is likely one of those.

Re: Factory Air??

I have the same compressor and mount on my dad's 80 GMC.
But,with the under dash evaporator and controls
The heater shut-off is universal and available in my parts books.(I used one on my 79 C-10.)
I like your in dash controls!
