How to replace the A/C Switch control module on 2003 Cadillac DeVille?

Try these steps initially when dealing with HVAC Control Module replacement: begin by taking out the instrument panel center trim plate. You must depress and hold four locking tabs that sit on the hvac control assembly corners before pulling the control forward from the instrument panel (I/P). First disconnect the electrical connectors from the hvac control before removing the hvac control assembly from the instrument panel location. Fitting the hvac requires connecting all electrical wiring during which time the ignition power should remain turned off to achieve correct actuator tuning. Install the hvac control assembly into the ip by sliding it into the ip opening until the retainers lock. Afterwards reinstall the instrument panel center trim piece. The vehicle must run for one minute without HVAC Control Module adjustments during self-calibration to prevent improper hvac functionality. Engine power keeps the system running to finish calibration correctly.
