Thought I would give you all an update on this. Unfortunately, the problem is STILL present.
The rinky-dink garage (don't know what else to call it!) that installed the AC compressor, decided to grasp at straws and told me that they believe the problem is in the electronics. They were able to get from the same used parts place as the AC compressor, on temporary loan/lease the part of the dash that consists of the speedometer/odometer/gas gauge displays, along with the climate controls on the right with the other push-button controls on the left (which I picked up for them, although I didn't think I should have had to.) They wanted to plug it in to see if that corrected the air issue, if it did not, the part would be returned.
They then had some difficulty getting the far left vent to come out of the dash, which is still not fully back in place 100%, I could not even get it to push in the rest of the way, they likely also cracked the plastic moulding on that vent at the lower left corner - I cannot say for certain though. Then said to bring the car back on Monday as they would need it for 2-4 hours.
I decided not to bother with them anymore and returned the part to the used parts yard - with a witness. I then went back to the garage, told them that I had returned the part and that I decided not to get it fixed. He kept asking me if I was sure, I told him yes, then also said that I would not be putting any more money into the car. I think at that point, he probably got the subtle hint that I would not be coming back.
My uncle is going to ask a friend if he can take a look at it and possibly remove the vacuum hose (and plug it), or replace that brake release diaphragm. I told him about what had transpired with the garage yesterday.
