BLEND-AIR DOOR ACTUATOR

CAUTION: Do not remove any of the motor actuators from the heater-A/C unit assembly with any electrical power applied. Removal should only be done with the Ignition OFF. The actuators have no mechanical stops to limit their travel. If the actuator rotates and is not connected to the unit assembly, it will become un-calibrated.

REMOVAL AND INSTALLATION

The blend-air door actuator is located on the A/C- heater housing above the floor hump.

(1)Remove under panel silencers.

(2)Remove the carpeted cover over the air bag control module.

(3)Remove floor air distribution duct.

(4)Locate and remove three actuator attaching screws (Fig. 2).

(5)Lower the blend-air door actuator from A/C- heater housing while removing actuator from blendair door shaft (Fig. 3).

(6)Disengage wire connector lock and unplug connector.

To install, reverse the preceding operation.

CAUTION: Align the blend-air door shaft to the slot in the actuator. Be sure the shaft on blend-air door actuator is properly engaged (when installing) to prevent damage.

Perform system check.

MODE DOOR ACTUATOR

The Mode Door Actuator is located on the side of the A/C-heater case near the accelerator pedal.

CAUTION: Do not remove any of the motor actuators from the heater-A/C unit assembly with any electrical power applied. Removal should only be done with the Ignition OFF. The actuators have no mechanical stops to limit their travel. If the actuator rotates and is not connected to the unit assembly, it will become un-calibrated.

REMOVAL AND INSTALLATION

(1)Remove under panel silencer.

(2)Disconnect electrical connector from actuator.

(3)Pinch and remove the lower plastic clip from the actuator arm (Fig. 4).

(4)Remove the three actuator bracket mounting screws (Fig. 5).

(5)Rotate actuator to gain access to upper plastic clip. Pinch and remove the upper plastic clip (Fig. 5) from the actuator arm.

(6)Remove actuator-to-actuator mounting bracket screws.

(7)Remove actuator from mounting bracket. Remove from vehicle.

To install, reverse the preceding operation.

FRESH/RECIRC DOOR ACTUATOR

The Fresh/Recirc Door Actuator is located on the passenger side of the A/C-heater case.

Fig. 5 Actuator Bracket Mounting Screws

CAUTION: Do not remove any of the motor actuators from the heater-A/C unit assembly with any electrical power applied. Removal should only be done with the Ignition OFF. The actuators have no mechanical stops to limit their travel. If the actuator rotates and is not connected to the unit assembly, it will become un-calibrated.

REMOVAL AND INSTALLATION

(1)Remove the glove box/ash tray assembly. Refer to the Switch and Panel Component Service section of Group 8E.

(2)Remove under panel silencer pad.

(3)Remove the carpeted cover over the air bag module.

(4)Remove the right front kick panel.

(5)Remove metal instrument panel brace (Fig. 6).

(6)Remove two screws mounting the actuator mounting bracket to the A/C-heater case (Fig. 7).

(7)Remove three screws holding the actuator to the mounting bracket (Fig. 8).

(8) Tilt actuator to release from actuator link. Remove actuator from vehicle.

To install, reverse the preceding operation.

IN-CAR TEMPERATURE SENSOR/ASPIRATOR ASSEMBLY

The In-Car Temperature Sensor/Aspirator Assembly is located behind the instrument panel and to the right of the steering column. The air intake opening for the aspirator is located to the right of the steering column (Fig. 9). The Sensor and Aspirator are wired together and must be replaced as an assembly.

REMOVAL AND INSTALLATION

Fig. 9 Aspirator Air Intake

(1)Remove the instrument cluster assembly. Refer to Cluster and Gauge Service section in Group 8E.

(2)Un-snap the sensor from the instrument panel (Fig. 10).

Assembly Removal and Installation

Ä

(3)Remove the two aspirator mounting screws (Fig. 10).

(4)Disconnect the aspirator intake hose from the instrument panel (Fig. 10).

(5)Remove sensor/aspirator and it's wiring harness from vehicle.

To install, reverse the preceding operation.

AMBIENT TEMPERATURE SENSOR

The ambient temperature sensor is plugged into a two wire receptacle in the A/C-heater housing behind and above the glove box.

REMOVAL AND INSTALLATION

(1)Remove glove box/ash tray assembly.

(2)Locate and remove two attaching screws on sensor receptacle (Fig. 11).

Fig. 11 Ambient Sensor Removal and Installation

(3) Carefully pull receptacle and sensor from housing.

CAUTION: It is possible for the sensor to hang up on the edge of the hole in the A/C-heater housing assembly during removal. This may cause the sensor to disengage from the receptacle and fall into the housing.

(4) Unplug sensor from receptacle.

To install, reverse the preceding operation and retest system.

HEATING AND AIR CONDITIONING 24 - 75

WATER TEMPERATURE SENSOR

The Water Temperature Sensor is located on the heater hose mounting plate between the heater hose nipples.

REMOVAL AND INSTALLATION

(1)The A/C-heater housing assembly must be removed for Water Temperature Sensor replacement. Refer to Heater-A/C Unit Housing Removal and InstallationÐAC/AY Body for procedures.

(2)Remove sensor mounting screw (Fig. 12).

Fig. 12 Water Temperature Sensor Removal and

Installation

(3) Disconnect the sensor pigtail wiring harness from the main wiring harness and remove sensor from vehicle.

To install, reverse the preceding operation. When tightening the sensor mounting screw, allow the sensor to rotate and contact the upper heater hose nipple (Fig. 12). This will aid in sensor efficiency.

ATC COMPUTER/CONTROL PANEL
