May need to be re-calibrated, and check the connectors by wiggling them when the door dosent re direct the airflow to the defrost setting. 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 Power and Recirculation buttons for at least five seconds. If equipped with the automatic temperature control (ATC) system, 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 Power 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. 3. The calibration procedure should take less than two minutes to complete for the manual A/C- heater control, and less than twenty seconds for the ATC A/C-heater control. When the LEDs or graphics stop flashing, the calibration procedure is complete. 4. If the LEDs or graphics continue to flash beyond the two minute (manual) or twenty second (ATC) calibration time, it indicates that the A/C-heater control has detected a failure and a Diagnostic Trouble Code (DTC) has been set. Refer to BODY DIAGNOSTIC PROCEDURES to perform further diagnosis. The LEDs or graphics will continue to flash even after the ignition switch is cycled Off and On, until a successful calibration is completed or until the vehicle has been driven about 13 kilometers (8 miles).
The other thing is, there is a tech bulliten about the a/c drain draining water to the passenger floor, instead of out of the vehicle, check the rugs on that side, are they wet?
