AC fresh air door actuator - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Everyone seems to be selling the fresh air actuator for the ridiculous price of $50 which seems totally insane.

Anyone had any luck finding a substitute off of another vehicle? There are so many that look like they would work for $10-$20 on amazon and other sites.

I saw the $50 one. I'll also wait to see if something less expensive shows up.

I did away with mine many,many years ago and closed off the cowl area so air can't come in it. It was one of the best mods I have done to my truck for the AC system. My truck run 38* just on low. That with 134-A in the system also.

Following along here, I've wondered about this before as well. In your mod, what/where exactly did you close off. I always get confused with all the doors, baffles, etc. Thanks.

The flapper out under the cowl vents that has the arm by the AC box. I sealed it off and I leave the manual cab vent on the passenger side inside the cab open which in turn lets the air circulate inside the cab keep it cooled down.
I read a thread on this many years ago on this forum about doing it.

I just bought one from Classic Parts. I didn't like spending $50 for something like this, but couldn't find anything else that would work. Possibly a cruise control diaphragm might be modified, but I didn't have anything to work with. I installed the one I bought and it worked and fit well enough.

Andy, What did you seal the vent with? Do you have pics?
