Default A/C blowing hot air

Help...it's 90 degrees out and my A/C is blowing hot air. I have a
93' coupe, automatic trans. Does it need a recharge? If so, this car uses the old R12 refrigerant....Thanks for the help guys!

Wow, not much information there to give you an answer. Does the A/C clutch pick up then drop out or not engage at all. Does blower run on high if you tell it to? Did it work yesterday or had it not worked for some time. Did it gradually get hotter or all at once.

A little more information and I'll bet these guys all jump in and help fix it.

Yes, does the compressor clutch try to cycle at all? If it is just low on refregerant, it will cycle frequently and not cool.

Does the fan control work, inside the car?


Here's a bump anyway
