NO A/C

[DUBBIN' 22''$]

Hello, I am trying to figure out why I have no cold air coming from my vents I tried putting freon in and still no cold air, when I turn it on it blows warm air, but when I crank it to the heat side it blows hot air, I have a 2002 5.3. Any advice and or help will make a huge difference. Thank you

All the vents are warm? If it's only one side, probably blend door actuator problem, very common. If it's all, probably refrigerant or compressor
