I have a 2000 Dodge Durango 5.9l V8 SLT which I have had since new. Recently My battery drained and ended up replacing the battery, and the same problen occured again so I replaced the battery again. I also had the alternator checked and this is supplying charge to the battery fine. Then I noticed the battery drains everytime I turn the AC on. Can anyone help?

 

sounds to me like you have something shorted, start pulling fuses until you see that drain go away and then check everything on that fuse to find it

Thank you all for your excellent advice. I will try them out this weekend and let you all know how it went. My personal feeling from what I have learnt is the Drive belt being loose or owrn out.
