(2) Disconnect the sensor at the wiring harness. To install, reverse the preceding operation. Snap

the sensor securely to the instrument panel.

POWER MODULE (PM)

REMOVAL AND INSTALLATION

(1)Disconnect the negative battery cable.

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

(3)Remove the four PM attaching screws (Fig. 2).

(4)Disconnect electrical connector.

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.
