Hello GM lovers,
 
I’m back again, with hat in hand, asking for help. Recently, I charged my a/c system back into the proper amount of coolant. Now living in the Desert, “cool” air is considered about 80 degrees on a 110 degree day. So all was fine while running the air. One day the blower motor decided it was done working. After schematic searching, I thought I would try the climate control module. That was not the issue. Then I optested the blower motor itself, and voila, it worked, so that lead me to belive it was the resistor. I changed the resistor, and had to rewire the harness, and blew the fuse. Changed the fuse, blower works. Air compressor kicks on, and I have cold freon going into the condensor. However, I am getting 100 degree air out of the vents.
 
Can anyone help? If I have forgotten something that I may not know of (because I may not know of it) please educate me

The blend door actuator may have failed.  Not uncommon, lots of videos available on where it is, and how to replace it.  But, I would suggest testing it to make sure it's the problem.
