To begin work on the HVAC control, slide the center bezel mask backwards from the front, along each side of the radio and A/C controls, so the clips come apart. Next, take out the control using an attaching screwdriver, unplug the two electrical connectors and control cables and remove the HVAC control from the instrument panel opening and the vehicle. To install, join the wire connector to the control head, insert the HVAC control unit into the center instrument panel opening and use the screws to fasten the control. After that, attach the power outlet connector and then center-align the bezel in the retaining clips, press down to snap it in place.
