70 Trans Am A/C vacuum actuators
Hey AlI, notice that the A/C Purge door stays open when it should be closed The canister that is on the car is a single vac line , but I have a picture of the original part looks like it has a second nipple or maybe a bleed port. Any ideas ????

Take the Vacuum pod off or unhook it and see if you can move the door.

Might be dual action of similar to later years, so it has completely in or out but also half-way.

Has to be the vacuum switch in dash. I would borrow a vacuum pump and hook it to the main vacuum feed to the HVAC control right on passenger side underhood for troubleshooting.
