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

You must first gather the HVAC Control Module by unscrewing the ashtray area before you can remove the HVAC Control Module trim plate by pulling both sides toward you. The HVAC Control Module requires the electrical connector removal of both itself and the ash tray connector before the module's screws can be unscrewed to extract it from the vehicle. Insert the HVAC Control Module into the trim plate before you install the HVAC Control Module screws and fasten them at 2 n.m with a pressure of 18 lb in. First reconnect both the HVAC Control Module electrical connector and the ash tray electrical connector after you settle the trim plate through pressing motion to activate tab engagement. Affix the screw behind the ashtray by using 2 n.m (18 lb in) torque force.
