I was having the battery die every evening, took it to a mechanic and he found that the ac relay was always on and that was draining the battery. Once the relay was removed, I have had no problems. Not sure if the relay is bad or if,it's the wrong relay, but I would like to fix to try and get ac in the car. This was given to me and the ac was never working because the relay was not in the car, my brother a relay and then the problems with the battery.

 

Sounds like it might just be a "stuck" relay? Try switching the cond fan relay with the ac compressor relay and see what happens?
