A/C Question, a new one
 

I have a weird problem that someone has to have a cure for. When I accelerate w/ the A/C on it quits blowing out of the vents. I can hear the fan blowing air but it sounds like a damper or something blocking the flow into the car. As soon as I let up on the gas it blows ice cold again. With the 134 conversion you could freeze meat in the car.

That is an easy fix !
You loose vacuum when you accelerate.
And since the AC door is control by vacuum, when you loose vacuum the door change direction(close the AC)

There is two one way valve on the brake booster. Black /Blue valve is for your AC.
Check your vacuum valve black/blue on the Booster brake.

I have a question. If they AC valve isnt on the booster where else could it be? I found my AC valve inside my glove box and I cant figure out where it went. My car has always had a problem with the vents blowing hot air when the car is running. Oh, sorry for hijacking your thread, lol.

What year car is it . Porsche might put it any where in the engine bay.
Like on the 83 944 N/A, the vacuum is from the intake manifold (pic. 1). And on my 86 951 see pic 2. http://forums.pelicanparts.com/uploa...1216116577.jpg
