How to replace the HVAC control module on Chevrolet Silverado 2500?

To replace your HVAC control module, first remove the instrument panel accessory trim plate, and the screws which fix the HVAC control module.

While installing the new HVAC control module, keep the key of the car in off position for proper calibration, plug the electrical connectors, and introduce the module into the instrument panel and ensure the retaining tabs are locked. Fasten the screws of the HVAC control module while tightening them to 1.9 N.m (17 lb in).

Start the vehicle and warm it up for a minute.
