Vacuum pot/actuator/canister for HVAC doors

I don't know of any fix for them, unless you can straighten the lip out and get to the diaphragm. However, they are called a vacuum servo. That might assist you in finding another one. I'm decent at findin stuff. I'll search too and see if I can help.

I appreciate that. It seems to be working decently now after I cleaned and greased the actuator rod but it would still be nice to know where to get those things. Right now the bigger issue is getting that door to close and seal properly in the right position.
