HVAC Control Module: Installation

WARNING: This page is about a different car, the 2002 Buick LeSabre. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The ignition must be in the OFF position when installing the HVAC control module to ensure proper actuator calibration.

NOTE: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted improper HVAC performance will result. The engine must be running for proper calibration to occur.

Install the HVAC control module and ensure that the tabs are fully seated to the I/P. See Figure. Install the right I/P accessory trim plate. Start the vehicle and let run for one minute to calibrate.
