Question:

Two front cooling fans are not working. If it is the fuse or relay, which one would it be? There are four in the fuse box please I am stuck in the Mojave Desert right now thank you

There are typically two cooling fans attached to a radiator, the high speed fan and the low speed fan. I looked in the owner's manual for your 2011 Ford F-150 and its does not specify which fuse is for which fan so you will just need to check all of the ones that relate to the electric fan circuit which I have listed for you below. The fuse will be more or less apparent if blown but the relay will be more difficult to check. If you switch the suspected faulty relay out for one that you know is working, you will be able to see if it is bad.

High/Low Speed Radiator Cooling Fuses:

#12 - 40 amp
#15 - 40 amp
#63 - 25 amp

High/Low Speed Radiator Cooling Relays:

#5 - N/A
#40 - N/A
#85 - N/A

I may be able to troubleshoot this but I would need a bit more information, such as the make/model of your truck along with anything you've tried already. Your best bet honestly is to just take it up to a local mechanic/shop to have them take a look.
