Plz help, what is/are the fuse(s) numbers/location and/or including relays for the AC in a F250 2001 Diesel pick-up truck

SOURCE: ford f-250 diesel

If the timer you have looks like a starter relay it is located at the back of the engine close to the fire wall. There is a little plastic cover over it that you can pry off with a screw driver. It has 2 large and 2 small wire posts on it. I had to replace the one on my brothers truck the other week. Hope this helps.

It should be under the hood.

I have a 1998 Ford Contour. Believe it or not the ABS and the Blower Motor share the same fuse. It's a yellow 60 amp and you have to take off the battery to get at it. Of course this happened twice in the 6 years I had the car, both times in the dead of winter. Tires Plus in Pennsauken, NJ replaced it. Other than that, no complaints with my Contour.

SOURCE: ac relay location in fuse box

you have to refer to the owner's manual. that is where they list the fuse/relay locations. if not there, you may need to refer to the diesel supplement book. but i think it will be in the owners manual. i have a 2002 f250 and that's where mine are.

If you don't have your owners manuel to find the fuse/relay location, you can go to flmowner.com and at no cost look at your owners manuel online.
If the fuse/relay is good the possibilities are the switch or the blower motor, with the blower motor being more likely.
If your blower works on high only (maybe not your case, just fyi), the problem is likely the blower motor resistor.
I hope this is helpful.
