Ac blowing warm air

2004 king ranch with edge programmer 250,000k. Ac is blowing warm air intermittently. No leaks in system just had a few hoses changed trying to find this problem out. It seems that when the coolant temp reaches about 205 the ac quits and then after a while after it cools down to 190 it starts back up. It seems like the truck thinks the engine is super hot and shuts the ac down. If the engine doesnt get that hot is blows great very cld air. The garage working on my problem are stumped. Anyone have a similar problem

can you pull any codes? Make sure your fan clutch isnt going south before you start tearing into your AC system.

If your fan clutch is good then have the garage pull the freon out and take a look at the orfice valve, if its crusted up then replace it and the drier. I had a truck that i was working on do the exact same thing. Turns out the previous owner put AC dye in it and left it. It then crusted up the orfice valve.
