Looking for parts for bathroom power vent
Today I was cleaning the roof of leaves and junk in preperation to clean the dirt and mildew off. The bathroom vent cover had some leaves caught under the flange and wouldn't blow out, so I decided to remove the cover and do a good clean-out. Once I got the cover off, I found that the inner crank-up lid was crumbling. The plastic was so brittle you could hardly touch it. The unit tag says Jensen mod. C775 on the little electric control box. Everything we've looked up so far, (RV supply houses, E-bay, etc.) only seem to have what to me looks like an exterior lid, 14X14. This inner lid measures 12 3/4 X 12 3/4. It cranks up, and the fan comes on. The exterior cover doesn't move, is sort of tear-drop shaped in the front, and square in the back, with downward slanted louvers. I suspect it's original, so most all Alpines should have one that is similar.
Any suggestions out there?
