My air was working before, I took it to the shop to get the rear main seal fixed and when I got the truck back my air started blowing hot air. I got a new climate control module and it still was blowing hot air. What else can it be?

Good afternoon.

Did you see if you have any pressure in the Freon system? It needs a minimum of 20 lbs to close the low pressure switch.

Also, check to see if any wiring was disturbed at the compressor.
