Yeah, Todd is right. Those 30.00 recharge kits are deffeintly worth a shot. Considering a regualr recharge at a shop is as much as 100.00+. And they do the exact smae thing... just a bigger machine.
Considering if they recharge the system and that does nto work, you are out 100 bucks or so. If you have a leak, be prepared to shell out, AC repair's are expensive. Also, may wanna stop by some well known shops that offer AC inspections, sometimes for free. They'll tell ya whats up.
Just a note... my old CSVT had warm air syndrome and a mechanic added the leak dye to it, never foudn the leak. THe condenser was shot and to replace it, $1100.00 parts/labor.
