Removal and Installation

1. Remove control assembly as outlined.

2. Remove knobs as required. Refer to Control Assembly Knobs Removal.

3. Remove component being serviced as follows:
   • Blower Switch—Remove one screw. Rotate switch in a counterclockwise direction to clear upper retaining flange. Then slide switch upward and out of its lower retaining flange.
   • Function Selector Electro Vacuum Switch—Remove one screw. Rotate switch clockwise until it clears its upper and lower retaining flanges. Lift switch so that location pin in its lower, inner corner clears arc-shaped slot in back surface of control assembly.
   • Illumination Bulbs—Each bulb has a moulded-in configuration which provides a go/no-go means of controlling bulb positioning in socket, as well as alignment of its electrical contacts with printed circuitry on backside of control assembly. To remove a bulb, twist in a counterclockwise direction and lift bulb out of socket. The temperature control cable mechanism should be moved completely to the right or left to permit access to bulb being serviced. The male connector for the bulbs is moulded into the control assembly.
   • Temperature Control Cable Mechanism—(The control cable will have been disconnected during removal of control assembly). To remove mechanism, remove retaining screw. Rotate assembly in a counterclockwise direction to free it from upper and lower retainers.

4. To install any of the components detached from the back of the control assembly, reverse Removal procedure.
