Recently started getting hot out and went to use my AC and it didn' work. Drove to auto zone and picked up a can of AC Pro and it was cold but not as cold as it used to get. This was yesterday, today went to use it and again didn't work. Tested the pressure, nothing. Refilled and ran the truck for awhile. Never messed around with the AC or Compressor so I wanted to ask what are common things on the truck that would go bad and cause the AC to not pump cold air.

 

Please add your vehicle details so we know what we are working with.

Sounds like you have a leak in the system, and your refrigerant is bleeding off. Given how quickly it happened, gotta be a pretty significant leak. Which makes it easier to find.....

 

I'm just hoping it's not the compressor. If it' an O ring or hose, awesome.
