[QUOTE=Tizzy1;2329278]A/C-HEATER CONTROL CALIBRATION

The A/C-heater control module must be recalibrated each time an actuator motor or the A/C-heater control is replaced. If the vehicle is so equipped, the calibration procedure also includes rear HVAC positions for each actuator motor.

1. Turn the ignition switch to the On position.
2. If equipped with the manual temperature control (MTC) system, press and hold the Rear Wipe/Wash and Recirculation buttons for at least five seconds. If equipped with the automatic temperature control (ATC) systen, simultaneously press and hold the Power and Recirculation buttons on the A/C-heater control for at least five seconds. The MTC A/C-heater control Rear Wipe/Wash button light emitting diode (LED) and Recirculation button LED, or the ATC A/C-heater control Delay and Recirculation graphics will begin to flash when the calibration procedure has begun.

Question. I assume that you're referring to the rear windshield wiper/wash button?

By "recirculation" button, are you referring to the AC recirculation button?

If the answers are yes, I tried this procedure multiple times and it didnt work at all. There were no flashing LED lights on the dash or the HVAC system as you mentioned. Please advise.
