My 2002 GMC Envoy blow warm air out of the Drivers side but the pass side is cold?

I have checked the Freon pressure as well as cleaned the coil in from of the radiator. When the air is turned on the passenger side and rear is cold but the driver side is warm Someone said there is some kind af switch where can I find it and how can I check it. Maybe there are two switches and I could just switch them to see if that solves the driver side then I can just by that switch

I have the same problem except opposite sides from yours. Did you get yours fixed if so what was the solution?

Last time we had that problem, and it was several years ago, the dealer had to replace some parts...BCM? But we had an extended warranty and didn't cost us anything..can't remember what was goofy.....sorry.
