I just spent 10 minutes posting what the problem was and when I went to add pictures the post disappeared along with my pictures. Darn it! Let me try again and if it doesn't work then heck with it.
Pull the fuse which operates this circuit first.
1. Remove light switch knob by pulling down.
2. Remove nut on switch's shank.
3. Remove screw from vent handle and remove handle.
4. Remove 4 screws located at edge of center grill. I don't remember mine having these.
5. Lower shade.
6. Remove center screen, I think it has 2 screws. You should be able to reach the micro switch which operates the fan when the vent is almost fully open. Check to see if it sticks. It just might need some cleaning.
7. If you can't reach it, remove the 5 screws that secure the reflector plate to the multidome.
8. Disconnect light leads from harness at the quick disconnect connectors.
9. Lower plate assembly.
10. I don't think you have to remove the fan assembly if you have small hands.
11. Remove 2 oval head screws on body of micro switch which secure it to vent frame. Clean her up.
12. To adjust after putting the switch back in or replacing it, adjust switch's leaf by bending. Fan switch switch should "close" (turn fan on) when vent crank is approximately 1.2" from full open position.
Hope this helps.
