Probably the left temp actuator. The wires in the right I/P junction block could have poor tension also, but it's usually the temp actuator.

I have a 2002 Envoy the drivers side air vent blows hot air and passenger side blows cold air not matter what the temp is set on

It's an ongoing problem with Envoy. I had the same problem on the drivers side not getting cold air. It cost me $600. They said it was a door inside the dash that diverts the cold air and the hot air depending on what you want. Worked good for a year, and now the passenger side gets cold air and not hot. Another $600 going out the door.
The repair shop said that sometimes they can adjust it, but most of the time they have to replace it. Good Luck

Air conditioner blows hot air after 30 seconds on drivers side, on start up. Passenger side works fine. Air blows out correct vents per setting on air conditioning. Replaced blend door actuator on drivers...

I have had this problem. I am not a mechanic...so to correct the issue temporarily, I simply turn off the car and restart. This has worked everytime for me. In extreme cases, I think you can also remove the AC fuse and start the car, which will also reset the computer. I also think that by taking the climate control off the "AUTO" setting has worked in the past.
