So if your fan isnt working on one of the settings (most likely low) then you probably need a new blower motor resistor.

This video will show you how to replace the blower motor resistor yourself nice and easy!

Let me know what you think!
**Also, if the video was helpful, give it a “thumbs up” on YouTube (it helps me out, thanks)***

 

well done video man, I had to replace the blower motor resistor in my girlfriends sport trac with the dual zone temp control, still easy to do but way more expensive, cost about $150-$175 for the part.

 

Thanks for posting/linking this. My blower fan only works on low speed only when driving for a couple hours, I'm suspecting I need to check the resistor out.
