Procedure help needed, 2001 HVAC climate control - single mode - actuator recalibration method

[Ray Elledge]

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.

I miss my '71 C-10. It had wire-in-sleeve to move the HVAC doors, the levers on the control were subject to breaking when the Sleeves weren't oiled.
