My AC is not cooling, The fan works sometimes.
Sounds like you may be having two issues. The A/C and the fan work completely independent from each other. The A/C is a sealed system that routes cold refrigerant into a radiator like part called an evaporator. The evaporator is located in your dash. The air you feel in your vents is the air that the fan blows across the evaporator. The fan is completely separate. It’s only function is to blow air. Depending on what you select, the air from the fan will be directed over a cold surface like the evaporator or a hot surface like the heater core. So you can have an issue with the A/C not working and a separate issue if the fan is only working sometimes. I would suggest seeking the help form a qualified mechanic, such as one from YourMechanic, to help determine the cause of your A/C issue.
