Having a little trouble getting my fan for my HVAC to work on my 96 f350, it works just fine on hi but thats all it works on. I think a mouse might have something to do with it. I usually dont drive it much in the winter time and i just pulled a mouse nest out of the fan itself, thought that was the problem but now it actually blows air but only on hi. any thoughts?? Thanks
My guess would be that the blower motor resistor is toast or the wires to it are bad.
It should be mounted on the blower box under the hood I would think.
what they said. The resistor pack is to the right and below the blower motor if you look at it from the front of the truck, there are 4 or 5 wires coming out of the thing.
