This could mean you need a refrigerant recharge, that you have a refrigerant leak, OR that the mixer valve is not working and that you're getting hot air from the heater core instead of the air conditioner.

The refrigerant is probably the quickest and cheapest fix. Take it to a local shop that does air conditioner work and have them test the refrigerant pressure (in psi). They'll be able to tell you if that will fix the problem.

Don't try to DIY and just buy a can of refrigerant as you can potentially over fill the system.

94 Buick Roadmaster AC fan blowing hot and won't shut off


If you have climate control it could be the main processor. Something could be shorting the blower relay to keep it on. You would also need to check and see if the system is still full of freon.
