To replace HVAC Control Module, you start with the removal of the instrument cluster trim plate bezel, the removal of the instrument panel storage tray, and the removal of the accessory switch assembly from the instrument panel. Then undo the screws securing the hvac control assembly and let out retaining tabs to pull out the control head of the instrument panel carrier. You are required to disconnect the hvac control assembly electrical connectors. During installation, let the key be in the off position so as to ensure proper calibration before connecting the electrical connectors to the hvac control assembly. Install the hvac control assembly and the accessory switch assembly to the paramount of the instrument panel and secure the hvac control assembly to the paramount with screws, twisting them to 1.9 n.m (17 lb in). Finally, install the instrument panel storage tray and the instrument cluster trim plate bezel. Do not change the control settings on the HVAC Control Module during calibration since interruptions will cause improper performance of hvac. Begin the running of the vehicle and allow it to run for one minute.
