Need help with recalibration procedure. Replaced the HVAC climate control - single mode system - front (part # 15060162) - for 2001 Suburban LT with reconditioned part. New NOT Available from dealer (does not have left-right temperature controls, single mode system with single wire harness connector). All analog knobs, not digital readout. Actuator motors will not enter recalibration procedure. When connected to the Dealer computer, all blend door actuators work correctly. All manuals and help forums do not cover this model.

Hey guys Just to describe what I am experiencing. Before I lost my AC, I would occasionally have my blower speed slow down randomly, or the blend doors would move to a different location, or would kick into recirculation. I would have to turn the fan down and back up to get it to come back, but sometimes it wouldn't work. At some point my condenser caught a rock and was leaking, so I replaced it. Worked fine for about 6 months, then suddenly no more cold air. I roll like this for over a year in the texas heat. Not being able to afford to fix it. Then randomly, it came back on! I was happy but didn't know what happened. Then it went off again and hadn't returned. Well since then I have change the compressor, expansion valve, dryer, pressure switch, condenser. Charged it but compressor won't pull vacuum. Clutch won't engage on its own so I have to bypass it at the relay, but still wont pump down, so I suspect the solenoid on the compressor won't engage either, which from what I can tell bypasses the compressor in an unpowered state. I have the suspision that my hvac control module has gone out. My truck is a 2016 gmc sierra 1500 with the 5.3 v8 gas below is all the information I can pull about this. Any assistance would be GREATLY appreciated.
