I have a 04' F150 4x4 XLT with Manual Heat/AC control. The problem that I am having is that the Fan will only run on settings 3 and 4. The Fan will not blow a bit of air on setting 1 or 2. I have checks fuses but there is only 1 fuse that supplies the power for the unit. Any Ideas? This truck now has 132k miles on it. I also have lost power via the passanger side power window (will nork via master driverside control but not from passanger side, even tried switch from back door on passanger side), I verified that the window lock feature is off but the passanger side front door window will not function.
