    Q:
    How to replace the A/C Switch control assembly on Cadillac Escalade? Posted by Customer
    A:
    Start by removing the instrument cluster trim plate bezel then the instrument panel storage tray before you detach the accessory switch assembly from the instrument panel. Begin by removing the screws from the A/C switch and release the retaining tabs before carefully pulling out the control head from the instrument panel carrier. Remove all electrical cables attached to the A/C switch. Ship the A/C switch by plugging in electrical connectors before returning it to its original location. First install the accessory switch assembly to the instrument panel while making sure you use the A/C switch screws that need to be tightened to 1.9 N.m (17 lb in). Reinstall both the instrument panel storage tray and instrument cluster trim plate bezel.
