Cabin Heater - Installation

INSTALLATION

NOTE: LHD model shown. RHD model similar.





1. Carefully install the positive temperature coefficient (PTC) heater unit (2) into the driver side of the air distribution housing (3). Make sure to position the two locator tabs on the end of the heater unit into the molded locator indentations on the right side of the air distribution housing.
2. Install the two screws (1) that secure the PTC heater unit to the air distribution housing. Tighten the screws to 1.2 Nm (10 in. lbs.).






NOTE: PTC heater shown removed from distribution housing for clarity.

3. Connect the wire harness connector (1) to the PTC heater unit (3) while pushing inward on the connector lock (2). Make sure the wire harness connector and lock are fully engaged.





4. Install the driver side front floor duct (7) onto the driver side of the air distribution housing (4) and install the retaining screw (8). Tighten the screw to 1.2 Nm (10 in lbs.).
5. Position the actuator mounting bracket (5) onto the air distribution housing and install the three retaining screws (1). Tighten the screws to 1.2 Nm (10 in lbs.).
6. Position the mode door actuator (2) and the blend door actuator (6) onto the actuator mounting bracket. If necessary, rotate the actuator slightly to align the splines on the actuator output shaft with those on the door linkage.

NOTE: If the retaining tabs on the actuator mounting bracket become broken during service, the alignment pins on the bracket bosses can be removed and screws can be used to retain the actuator to the bracket. Once the alignment pins are removed, pre-made holes can be found the center of the bosses, exactly where the pins were. This assures correct actuator alignment to the bracket. Use care not to overtighten the screws and damage the bosses.

7. Engage the retaining tabs (3) that secure the mode and blend door actuators to the actuator mounting bracket. Make sure the retaining tabs are fully engaged.
8. Connect the wire harness connector to the mode and blend door actuators.
9. If equipped, install the silencer below the driver side of the instrument panel Instrument Panel - Installation.
10. Reconnect the negative battery cable.
