I have an 04 F150 and can only use the #4 position on the control switch for the fan control? Auto Zone said it was the blower resistor switch for the blower motor??? Doesn't seem right to me since I still have one position on the control that works? Does anyone know what I might need??


Thanks.

 

Sounds possible...

 

Its the blower motor resistor that is exactly what happens when the resistor goes out. There is no doubt in mind mind! Its pretty cheap too.....I work at NAPA and its $24 at my store.

 

Yes it is the resistor. Setting 4 gets power straight from the battery.

 

I am having the same problem but mine works on 3 and 4 would it be the same thing?

 

Same on my 04 only works on 3 and 4.... Is it hard to install

 

If it isn't working on 4 its probably a wiring prom from the battery to the blower. If its not working on 3 or 4 then it could be the rheostat/resistor or the swith or a wiring problem.

 

its not hard to install the resistor. It's in/behind your glove box. 2 screws and a connector. Done in 15 minutes.

 

Any one know the part number. I would love to get this fixed.. i have to turn thwe radio up to hear when its on 3 or 4 and would like to have the lower number fan speeds.
