If the suction line is ICE COLD, check for a blend door problrm, what was done to the car before it began blowing hot air? any work under the dash? Or hood?

No temp door I know of uses vacuum- either cable or electric actuator-- look for loose cable- or bad actuator- take either loose- move temp door by hand.....see if it shuts off at either full cold and full hot....

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
