2001 Chevy Silverado Z71

Our truck’s air conditioner has stopped working and blows hot, and i mean hot, air!

The belt is fine and it has freon. Any suggestions? Thanks a bunch.

What are the pressures, static or running? Just because there is freon, doesn’t mean there is enough. The AC system has pressure sensors, and will turn off the compressor if the pressures get too high or are too low. If you don’t have the equipment to check the pressures, please go to a good independant professional.

How do you know it has the correct amount of refrigerant (it’s not freon anymore)? I repeat, how do you know?

Please answer this question.

Once again, BustedKnuckles is right, you need to take this vehicle to an automotive AC specialist. This is NOT a do-it-yourself project.
