Alright guys, I’m at a loss. Don’t know what do to from here. I’ve got a 2019 F250 with the 6.7. It’s been having some AC issues.

first AC recharge I got they couldn’t find any leaks, but it only lasted 2 days. Second recharge I got lasted 2 months without issues until today. Ac still blows a little cold, but warmer than it should be. With the AC on, the radiator fan revs with the engine. It sounds like a full size semi screaming down the road with the fan matching the engine RPM. If you turn the AC off, the radiator fan goes back to normal duty. Shop couldn’t find any AC leaks again either, even though they pumped a ton of dye into it last time it was there.

Anyone have any idea what it could be? Thanks!

 

Well, I'd say you need a different shop to look at it.
And, die is only good for places you can see, quite a lot of places in the a/c system you can't see.

 

Could it be over charged? What do the gauges say? Any codes?
