Thanks for info everyone on the bathroom fan it really helped, I was able to climb on top and found the plunger on the corner, driver side, hinge side of vent cover. I used a 3/8 wrench and pulled up on the electric wire and cleaned the plunger and sprayed it with silicone spray it was corroded. This info might help others my fan was stock and is 5/07 Model # B8100 Create-A-Breeze made by Fan-Tastic vent it was bought out by Dometic (800)521-0298. Plunger part # K1122-05. I have a extra it seems it the weak link on the fan.
