78' Air Conditioning
I know it could be many things but just wondering where to start with air con that just blows warm air. I just got the vette in May so have not really tried until it got really hot recently.

Take it to a mechanic with a/c certification and have the Freon levels checked. That is the starting point. They can also put in an additive that show any leaks you may have. Good luck and stay cool!

Yeah I'm thinking that's the best way to go before I do something I'll regret. Thanks.
