I have a 1991 Fleetwood that usually treats me fine. After driving my car I parked it and all was well. The heater worked fine that night but the following morning when I started the engine I had no heater at all. There is no digital readout displayed at all. I have felt the heat at the floor but with no fan blowing it. I looked at the fuse box for a blown fuse but can find no fuse with heater marked on it. There is one for the A/C but that one is fine. Any suggestions as to what the problem may be?

maybe ur heater fan went or the relay ...........i have a seville and i get the same problems but mine is dat it works when it wants to.......it manually shuts off as soon as it reaches a certan temp........but i think it has to be ur fan............
