OK first of all I would like to thank you for having this site up!!!!! As stated I have a 2002 T/B LTZ EXT and my A/C is starting to do some crazy things to say the least 
Well first of all my system is an automatic dual zone system, but my problems are that the drivers side will only blow luke warm to hot air, the passengers side will only blow hot air and the back seat controls will only blow hot air. Defrost and Recirc functions properly when I use them, I have disconnected and removed the passengers side actuator and it will blow A/C fine out of the passenger front side only. So I have all vents off and the passenger side one on with the recirc function so it will stay a tolerable temp, well tolerable for me not my wife and kids and my furry mutt all the way in the back!!! I have tried to recalibrate the actuators manually to no avail and even tried to turn on the ignition, and then simultaneously press the MODE, FRONT DEFROST and REAR DEFROST switches, that just changed my temp reading for a few hours to -39 then went back to displaying 50(friends suggestion and after we did it he said he didnt know what it did). During the winter when the temp falls below 50 the temp will display the proper outside temperature, I need your help as my wife is hounding me to get this fixed now that the hot weather is upon us. If it's the actuators does anybody have the real part numbers for my style so I dont spend an insane amount, I've seen a huge difference in actuator prices. Thanks for the help!!!!!
