A/C problem

[Krnmackmattsta]

say i have a 92 240sx.

The A/c blows but the air is kinda lukewarm. What do i have to do to fix it and how much?

thanks

is the system full of refrigerant?if it has r-134a and is low, it will cost a few bucks to refill.if you have r-12, then the refrigerant costs about $50 a bottle vs. r-134a being about 3.

Yeah, it definitely needs more diagnosis. Could be low on R-12, or it could be a bad compressor, or a bad temp switch or a bad pressure switch, or a bad relay, etc. The cost varies too. It won't be cheap though. Most of those problems require evacuating/recharging the system. It'll probably cost over $100 minimum, and maybe up to $700 to fix *right*. Cross your fingers it's just a bad relay.
