Instrument Panel Register Housing, Door and Thumbwheel Assembly
Removal
Remove instrument panel louver assembly as outlined.
Using a screwdriver, pry two upper and two lower tangs in housing out of
their seated positions in instrument panel assembly.
Pull housing out of opening in instrument panel.
If thumbwheel is to be removed, insert a screwdriver between wheel and
housing and twist it so that wheel and its wheel retainer will be pressed off
their stub shaft.
An arm which is integral with the wheel has a tang near its rear edge which
rides in an arc-shaped slot in register door to open and close door. When
thumbwheel and retainer are forced off stub shaft, it frees tang from slot in
register door. To remove door, flex it so that retaining tang in each upper
corner of door is pulled out of its mounting hole in register housing.
Installation
To install door, place it in register housing. Flex door so that its
mounting tangs may be inserted in holes in register housing.
Place thumbwheel and retainer over stub shaft in housing. Engage tang on
thumbwheel arm in arc-shaped slot in door. Press thumbwheel and retainer into a
fully-seated position on stub shaft. Rotate wheel to ensure that register door
operates properly.
Insert louver into register housing and press it inward (until it fully
engages with retainer in each side of housing).
