Is there an A/C drain on a 2004 cavalier,is sport if so where?

Best way to check for a drain on battery is to disconnect negative terminal and run it through a DC amp meter. Any current going out will show on meter. Then you can pull fuses one at a time and find the drain. Another, probably as effective way as mentioned before on CarGurus is to use a small 12 volt bulb to check for current drain.

No water in car,no water when I run A/C,Im thinking drain hose is pluged. I just was t rying to find drain hose,so I can unplug it..

its on the bottom of the firewall. on the passenger side.
