  Q: How to replace the HVAC control module on Buick Rainier?

  A: Beginning HVAC control module replacement requires removal of the I/P accessory trim plate along with the screws that fix the HVAC control module into place. While removing the HVAC control module from the I/P use a finger to push down the three tabs. Disconnect the electrical connectors from the control module. The installation process starts with connector attachment to the HVAC control module while tabs demonstrate secure integration before placing the HVAC control module inside the I/P. Fasteners need to use their designated locations because replacing them demands fasteners which precisely match the application's part numbers. Service documentation identifies the fasteners along with thread locking requirements and sealing needs. The application of paints, lubricants or corrosion inhibitors to fasteners or their joint surfaces should be avoided because these substances can compromise both torque values and clamping force and ultimately degrade the fastener. Always use the specified torque sequence together with the recommended specifications to protect the system from damage when installing new fasteners. Secure the screws on the HVAC control module at 1.9 Nm torque (17 in. lbs.) before reinstalling the I/P accessory trim plate.
