martiankat......On my 05, the indoor switch is in a cabinet above the entry door. To the left of that is a control box (about twice as thich as a deck of cards) in the cabinet over the dash. When you look in that cabinet the box is agianst the side wall. I haven't looked in awhile, but there may be a fuse in that box.
You also want to disconnect the outside cable from the motor home sidewall, make sure its clean and reinstall tightly.
