HVAC Refresh
I bought an HVAC vacuum hose kit from Dr. Rebuild (which I am very satisfied with) and I started installing it today. After confirming I have air where I should except for the floor vents, I think I found the issue. The spring connected to one of the actuators is broken and was just hanging there. Where can I find just this spring? The actuator seems to work fine.
The other thing. There was duct tape covering the 1/2" gap between the defroster duct and the center piece pictured. Should there be an intermediate piece there or was duct tape installed from the factory? I'm trying to do this right, and avoid taking my dash apart any more. It's a job I don't enjoy!

It has been noted here before.
The connection between the defroster duct and the ac/heater unit leaves a lot to be desired. Most people wrap ac tape or duct tape around it to seal the gap.
Good luck with the spring search. I know that you can buy the vacuum canister from numerous Corvette suppliers if needed.

Spring is gm #14001506.

If you look in the AIM, there is no such taped connection.

That makes sense. Thanks so much for posting. I was about to tape it up and make the same mistake someone in the past had done!

The gap on my '68 was much smaller. It was about One quarter to 1/2 inch. I chose to seal it shut with heavy duty duct tape. I would rather have the air moving in the right place. I looked through my photographs and cannot find a good image of what I'm trying to describe.

I used foil tape. Although I understand the logic, I don't see it. The blower is on the other side of the firewall.

Before I totally finished installing everything, I sucked on each of the new hoses to test for functionality of the actuators. Everything worked great except for the oval shaped door in the passenger side kick panel.
I took the actuator off, thinking that was the culprit, but the door is actually what's frozen in place. Actuator tested fine. I tried to move it by hand, but I couldn't do it. Is it common for these to freeze up? How can I get it to move again?
