    Q:
    How to Replace the A/C Switch in an Automatic HVAC Control Module on Buick LaCrosse? Posted by Customer
    A:
    In order to replace HVAC Control Module one has to first remove the instrument panel lower trim plate and the HVAC Control Module mounting screws ensuring that retaining clips hold the module in place. Pull the HVAC Control Module backwards away from the instrument panel and detach the electrical plugs. When you remove the module, make sure the key is in the off position before you attach the electrical connectors to the new HVAC Control Module. Mount the module using the mounting screws and tighten them to 2 n.m (18 lb in). Finally, reinstall the lower trim plate of the instrument panel without any manipulations with the HVAC Control Module controls at calibration for the propriety performance. Run the engine and let it run for one minute, to finish the process and follow the required programming and setup information.
