• Q: How to Replace an HVAC Control Module on 2002 Chevrolet Suburban 1500?

  A: To replace the HVC control module, first, take an instrument panel accessory trim plate and screws to secure the HVAC control module. Press the control assembly retaining tabs to remove the HVAC control module from the instrument panel, then disconnect the electrical connectors. For installation, plug electrical connectors into the HVAC control module, and reinstall it into the instrument panel with retaining tabs locking into position. Put the correct fasteners in their proper locations because replacement fasteners must be for the correct part number for the application. Do not use paints, lubricants or corrosion inhibitors on fasteners or their joint, as they may impact on torque and clamping force and may damage fasteners. Follow the correct tightening sequence and specifications to avoid parts and systems from getting damaged. Fasten the HVAC control module with screws to 1.9 N.m (17 lb in) and then reinstall the instrument panel accessory trim plate. Disruptions to the smoke control mechanisms may occur, as it is important not to calibrate any controls on the HVAC control module. Last but not least, start up the vehicle and let it run for a minute.
