Kitchen and Bathroom fans

Have a 2003 Fleetwood Providence that has the Max Air fans in the ceiling fans located in bath room and kitchen ceiling area.(sure older model no remote) Both are not working. They both have fuses located on them. Both fuses are good. There must be a main fuse that supplies power to both. Tried checking the fuses in both areas by the brake peddle and in bedroom area. Boy alot of fuses to check. Can anyone help narrow the search area down for the bad fuse.
Thanks for the help.
