Replace thermostat. The current one temperature is too high for your trucks computer parameter or it’s defective.

I had the exact same problem. 2013 FX4. 3 low cost fixes. #1: check fuse #27. #2 replace the AC switch (autozone has it for $25). #3 replace the AC expansion valve. I ordered the part for $35, and had a mechanic install, vacuum and recharge the system and that fixed it for me.

2013 f150 fan coming on and staying on for long periods of time. Super loud. Checked fuse #27 thanks to the last response. I believe it fixed the problem.

I have a 2011 Ford F-150xlt with the 6.2. As soon as I turn the ac on my radiator fan kicks on and is really loud. I’ve been told that it doesn’t seem normal. Has anybody had the same problem and could you possible tell me how to fix it?

It’s the thermostat The one that’s in it is a little too hot , when I purchased this truck the previous owner said it was never in the shop, wrong..some one put a after market thermostat in it and the computer reads hotter than normal temp and kicks it on high speed. Get the Ford stat required for this at the dealer. Trust me, I tried everything and this was the fix..
