How to replace the HVAC control module on Buick LaCrosse?

The first step to switch the HVAC control module requires removal of the instrument panel lower trim plate. The next step involves removing the HVAC control module mounting screws where the module is retained by clips. The HVAC control module must slide backward from the instrument panel to disconnect its electrical connectors for removal. The HVAC control module installation requires the key to be in the off position during connector connection. Place the module in position before tightening 2 N.m (18 lb in) mounting screws. You need to install the instrument panel lower trim plate as your last step.
