108 Heater Lever Removel
1. Remove the glovebox. You need to press the center of each plug around the
front inside edge of the box thru (be sure to note where they go, you'll
need them later).
2. Unscrew the glovebox door from UNDER the dash, four
screws in all.
3. Remove the arms that limit how far the door opens and set
aside.
4. There is a rubber boot acting as a duct for air to flow thru the
center vent. You'll need to carefully press the keepers out from inside the
boot, I used a long screw driver stuck thru the front of the center vent.
There are two on top, two on bottom (if memory serves...)
5. Remove the four
square knobs from the levers. They will come off by rocking them from one
side to the other.
6. Remove the fan blower speed knob. Mine pulled straight
out.
7. Look into the center vent, at the outer sides near the top. In there
are screws about 1 inch or less inside the vent that need to be removed.
Remove them.
8. There is another screw that attached the vent lever to the
vent door. Unscrew it to disconnect the lever. It is also an adjusting
screw, so when you put it back together, you can set how tight the door
closes. This will be a great improvement if you have been hearing a whistle
due the door not closing prior.
9. The controls should be loose now. You can
carefully pry the four cable ends from the controls using a flat screw
driver.
10. Carefully remove the fiber optics that provide illumination,
remembering how they go back in for reassembly. I may have forgot something
in there, but you should be able to handle it as it comes up. The most
mysterious part is the screws removed from inside the vent. I tried this on
a car in the wrecking yard that had a bad dash first, well worth the $1 to
get into the Pick-&-Pull!
