Fresh air actuator vaccum line - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I removed my glove box and noticed the fresh air actuator in the kick panel does not have a vaccum line hooked to it. I don't see a loose line anywhere. Where would the other end of the vaccum line hook up to? It is an A/C (1979)truck but the PO removed the compressor.

On my 70, the pass side kick panel vent is used for recirculation. Hooks up to the AC controls.

EDIT:
On my truck, it is called AIR Inside. I believe on your truck it may be MAX AC. If the AC isn't working, you may want to see if you can get a pull handle from a non-ac truck.

It should go to the molded vacuum connection on the back of the Heater/AC control block.
