This was just a theory before people spend money on clamps and valves.
I work in a big store where things are sold on pallets. Some of the giant coolers have a roll-up door run off a motor and a small computer. The computer counts rotations of the motor to know when the door has rolled all the way down to shut off the motor. It knows all the way up based on a lever it hits.
If you manually adjust the door up a foot off the ground and then hit the open switch, the door will roll all the way up, but when it goes to close, the door will stop at a foot off the ground.
I was applying that logic to the blend door as after I did this, I did get cooler temps. What is odd is now it is back to the way it was. Sometimes I get freezing air out of the vents, and sometimes I get cool air.
We seem to have isolated this issue to the blend door - how can we focus on that instead of clamping or shutting off the heater core? Has anyone peered up into the cabin air filter box to see what is reachable from there? BTW, I am just spit-balling ideas here.
Yes, you might be on to something and this theory is not far fetched at all, thank you for that.
About checking the doors physically if someone more mechanically inclined could access them then we might find other less invasive solutions.
