The climate control assembly is a single module packaged in the instrument panel console of the vehicle. It is a microprocessor-based control consisting of a bezel assembly (including all buttons and switches), a main control board and a housing for the unit.
The climate control assembly provides the following driver interface controls:
- Climate control assembly ON/OFF switch/ fan speed switch
- Manual temperature adjustment switches (drivers/passengers)
- DUAL temperature selection switch
- DEFROST switch
- Heated front screen ON/OFF switch
- Heated rear screen ON/OFF switch
- Manual air distribution MODE switch
- Fahrenheit/Centigrade option switch
- AUTO mode switch
- A/C selection switch
- Recirculate air switch
Operating any of the climate control assembly controls activates a chime emitted from the instrument cluster.
The climate control assembly automatically maintains a selected temperature for the interior of the vehicle. The system regulates the volume of airflow between the instrument panel registers, floor console registers, front and rear floor ducts, windshield defroster and side window registers. The system can automatically select between fresh and recirculated air with an optional manual override. The climate control assembly will try to provide both driver and passenger with their selected temperature for comfort. The fan controls and air distribution are not controlled individually.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
