I have a 01-F350 Super Duty, the other day the door locks would not work with my keyfob, as I was in a hurry I just figured it was my keyfob battery. I changed it, still wont unlock or lock. Then I hit both driver side & passenger side switches. They ( all 4 doors ) are trying to lock and unlock but just move a hair and not like they should. I checked the fuse # 26 - big yellow 20 amp fuse out under the hood. It was not blown, I cleaned the terminals, still nothing. I then replaced it with a 30 amp fuse just to try that, still nothing. Im a bit baffled, am I missing something?? Any help would be great.

 

Pretty common problem. Check out this thread: https://www.ford-trucks.com/forums/4...cks-fixed.html

 

Thanks so much for the info. Gonna have to set aside the time to fix these things. Might wait till november when the weather is nasty out.
