OB Mechanics..AC problems on gmc sierra

I have a 2006 gmc sierra that the passenger blows hot air while the drivers side continues blowing cold. I just replaced the blend door actuator under the glove box and the problem continues.. what's the deal? This Louisiana heat is killing me! Please help.

Common problem with several possible causes. It is intermittent when doing this?

There are two actuators. The one on my old 05 Tahoe was way up in the dash. Had to take the airbag out and everything. That had a center console in it
They are also very picky about how you put them in. Did you match it up perfectly with the old one? Did you run through the cycles of hot and cold a bunch of times? Also, I have heard stories of a bunch of them being bad out of the box.
Can you hear it switching?

HAMMERTIME NAILS IT. I just fixed my 04 Yukon with the driver side blend door actuator. takes about 20 mins to replace. YouTube is your friend. My A/C would be doing just fine, I heard clicking, then hot air on the drivers side and continued cold on the passenger side would ensue. Sounds like your issue as well.
