The Automatic Temperature Control (ATC) single zone heating-A/C system uses electrically operated controls. These controls provide the vehicle operator with a number of setting options to help control the climate and comfort within the vehicle.

The A/C-heater control (1) for the ATC single zone system automatically maintains the interior comfort level desired by the vehicle operator. The ATC system uses an infrared sensor located in the front overhead console to measure the surface temperature of the driver and front seat passengers. Based on the sensor input, the ATC system automatically adjusts air temperature, airflow volume, airflow distribution and amount of inside air recirculation to maintain occupant comfort, even under changing outside weather conditions. All controls are identified by International Standardization Organization (ISO) graphic symbols.

This ATC system offers several manual override features such as fan speed and airflow distribution. When the outside air contains smoke, odors, high humidity, or if rapid cooling is desired, the interior conditioned air can be recirculated within the vehicle.

The ATC A/C-heater control and integral computer is located in the instrument panel and contains

1. a rotary control for manual and automatic blower motor speed selection and for turning the heating-A/C system on and off (2). This control also contains a push button function for recirculating the conditioned air. The control contains an indicator lamp that illuminates when the heating-A/C system is in recirculation mode.
2. a rotary control for temperature control of the discharged air (3). This control also contains a push button function for manually turning the A/C system on and off. The control contains an indicator lamp that illuminates when the A/C system is in operation.
3. a rotary control for manual and automatic mode control of the discharged air (4). This control also contains a push button function for turning the rear window defogger system on and off. The control contains an indicator lamp that illuminates when the rear window defogger system is in operation.

The ATC A/C-heater control obtains vehicle speed, engine speed, engine coolant temperature, ambient temperature and refrigerant system head pressure data and is diagnosed using a scan tool. Refer to DIAGNOSIS AND TESTING .

Prior to replacing the A/C-heater control, check for any Diagnostic Trouble Codes (DTCs) related to the heating-A/C system and run the Actuator Calibration function using a scan tool to verify that the concern is not an air door calibration issue. Refer to STANDARD PROCEDURE .

The A/C-heater control cannot be adjusted or repaired and must be replaced if inoperative or damaged.

Scheme 17

The Manual Temperature Control (MTC) single zone heating-A/C system uses electrically operated controls. These controls provide the vehicle operator with a number of setting options to help control the climate and comfort within the vehicle.

The MTC A/C-heater control and integral computer is located in the instrument panel and contains

1. a rotary control for fan speed selection and for turning the heating-A/C system on and off (2). This control also contains a push button function for recirculating the conditioned air. The control contains an indicator lamp that illuminates when the heating-A/C system is in recirculation mode.
2. a rotary control for temperature control of the discharged air (3). This control also contains a push button function for turning the A/C system on and off. The control contains an indicator lamp that illuminates when the A/C system is in operation.

Two relays (1) are used for the electric Positive Temperature Coefficient (PTC) heater system when equipped with the 2.2L diesel engine. The relays are International Standards Organization (ISO)-type relays. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal functions and patterns (2). The PTC relays are electromechanical devices that switch fused battery current directly to the heating elements of the PTC heater unit. The PTC relays are energized by control circuits of the Totally Integrated Power Module (TIPM).

The two PTC relays are located below the left front fender in the diesel accessory fuse/relay block.

An electric Positive Temperature Coefficient (PTC) heater unit (1) is used on vehicles when equipped with the 2.2L diesel engine. The PTC heater unit aids in passenger compartment heating by compensating for the lower engine coolant temperatures produced by the diesel engine. The PTC heater unit is mounted in the HVAC air distribution housing, downstream of the heater core and is controlled by the diesel Engine Control Module (ECM) and the Totally Integrated Power Module (TIPM) through two relays in diesel accessory fuse/relay block located below the left front fender.

The PTC heater consists of a molded plastic mounting plate (2) with an integral wire connector receptacle (3). Concealed behind the mounting plate are four heating elements with fins (4) that transfer the heat produced by the PTC heater to the conditioned air flowing within the air distribution housing. Two retaining tabs (5) are molded onto the opposite end of the heater unit to support the heater unit inside the air distribution housing. The PTC heater unit is connected to the vehicle electrical system through the instrument panel wire harness.

The PTC heater unit is accessed for service by removing the instrument panel.

1. Disconnect and isolate the negative battery cable.
2. Remove the instrument panel. Refer to «PANEL, INSTRUMENT, REMOVAL»(ref-612710-S09852678672014043000000) . NOTE: To disconnect the wire harness connector from the heater unit, pull downward on the connector lock while pulling the connector away from the heater unit.
3. Disengage the wire connector lock (2) that secures the wire harness connector (1) to the positive temperature coefficient (PTC) heater unit (3) located on the left side of the HVAC air distribution housing and disconnect the connector from the heater. NOTE: LHD model shown in illustration, RHD model similar.
4. Remove the two screws (1) that secure the PTC heater unit (2) to the left side of the HVAC air distribution housing (3).
5. Carefully remove the PTC heater unit from the air distribution housing by pulling it straight out of the housing.

Note. LHD model shown in illustration, RHD model similar.
