Heater motor
Removal
1. Disconnect the negative battery cable (Chapter 5, paragraph 1).
2. Release the four clips (pulling them out) securing the passenger footwell upper trim panel. Then remove the panel.
3. Disconnect the engine wiring harness electrical connector.
4. Lift the motor locking tab slightly, turn the motor counterclockwise (viewed from below) - about 30°, and then pull out the assembly.
5. The motor control resistor can be removed by inserting a thin screwdriver into the slot on one end. Push the screwdriver in about 5 mm, overcoming the spring force, and remove the resistor (see Fig. 9.5).
Installation
6. Installation - in the reverse order of removal. Install the engine, turn it clockwise so that the locking lug is securely fixed (see Fig. 9.6).
Heat exchanger
Removal
7. Disconnect the negative battery cable (Chapter 5, paragraph 1).
8. Apply the parking brake. Raise the front end and support it. Drain the cooling system (chapter 1).
9. Disconnect the coolant hoses from the heat exchanger pipes protruding from the engine compartment bulkhead (see Fig. 9.9, a, b).
10. Working inside the cabin, remove the trim panels from each footwell in the area forward of the center console only. Each of these panels is secured with two screws. The center console can be removed to provide additional space (Chapter 11).
11. Remove the screw located at the base of the heater unit to release the air duct (see Fig. 9.11).
12. Remove the three slotted head screws (T20) securing the air distributor to the lower heater cover. Then release the clips. There is one plastic clip on each side, but metal clips may also be installed. Press the air duct to retract it and pull out the air distributor (see Fig. 9.12).
13. Release the clips - one plastic one on each side. (You may also find metal clips.) Then pull out the lower cover of the heater unit together with the heat exchanger (see Fig. 9.13).
14. Loosen the screw and remove the clamp to separate the heat exchanger from the bottom cover (see Fig. 9.14).
Installation
15. Installation - in the reverse order of removal. You may need additional metal fasteners to secure the lower heater cover and air distributor. Make sure that the air duct exits the air distributor downwards and is secured with a screw.
16. Fill the cooling system with a mixture of antifreeze and water (chapter 1). Start the engine and after it has warmed up to normal operating temperature (when the upper radiator hose is hot), recheck the coolant level and top up the system if necessary. Then check for leaks. Monitor the operation of the heater.
Driver side deflector and center deflector
18. These deflectors are removed together with the front panel trim (Chapter 12).
Front passenger side air vent
19. Remove the glove box (Chapter 11).
20. Remove the deflector from the end of the panel using a screwdriver, placing a gasket between its tip and the panel.
21. Disconnect the air duct from the deflector through the glove compartment opening and remove the deflector.
22. Installation - in the reverse order of removal.
