  Q: How to Replace the A/C Switch in a Manual HVAC Control Module on Buick Rendezvous?

  A:

  The i/p cluster trim plate bezel must be removed before removal of the retaining screws which secure the HVAC Control Module. Remove the HVAC Control Module through the i/p opening then unplug its electrical connector. Connect the electrical connector only after putting the key in the off position to perform proper calibration of the HVAC Control Module installation. Funnel the HVAC Control Module into its i/p position before securing it with retaining screws while tightening these screws to 2.5 n.m (22 lb in). After replacing the i/p cluster trim plate bezel you should reinstall it. Self-calibration requires that drivers keep all HVAC Control Module settings untouched since improper hvac operation could result. The system needs one minute of continuous engine operation before calibration completes successfully.
