Bad Cruise Control Check Valve. Pic related

all of the hoses under the hood are connected and good, and my cruise control works fine still. With that known, could it still be this valve? Thanks

OK fine. It's literally anything else. Go knock yourself out.

Shit i apologize you were so right. I've been working on this for many months and the interwebs all told me different things to do and now my dash is off and car is crazy. Leave it to 4chan to give a one sentence answer that is correct to a hardship in someones life.

I take it back. I replaced the check valve just now and it did not solve the issue.

what would an '89 blazer look like with swamp coolers

Im going to steal one from a louisiana trailer and mount it in the passenger window in a few weeks

as this lovely picture demonstrates, this actuator is filled when the switch is in the "off" position, and it moves inward when i move it to any other position. i will take another look and see if it moves in more depending on the setting. Is this the only one that determines the path of the cabin air, or the blend door actuator?

Okay i confirmed that guy is good. The one above it needs to suck that bastard in more to make it blow out vents. I was able to grab it with my fists and pull it out down and replicate vent air. I think it might just have a leaky diaphragm. Another trip to advance here we go!
