How to Replace the A/C Switch in an Automatic HVAC Control Module on GMC Sierra 1500?

The replacement process for HVAC Control Module begins by uninstalling instrument panel accessory trim and HVAC Control Module mounting screws and retaining tabs. Compressing the holding tabs on the control assembly will free the HVAC Control Module from the instrument panel before disconnecting all attached electrical connectors. Proper calibration requires the key to remain off position when you join electrical connectors to the HVAC Control Module for installation. After placing the HVAC Control Module into the instrument panel slot you must ensure that retaining tabs lock in position before installing screws to tighten at 1.9 n.m (17 lb in). Reinstall the instrument panel accessory trim plate while starting the vehicle to run for one minute with no HVAC Control Module adjustments to prevent inadequate hvac system operation.
