This may take some time to diagnose,you will have to have a power draw test to find what is eating the battery,you will need to have a 12 volt meter and pull one fuse at a time out of fuse panel while wacthing the meter to narrow the draw to find your issue.

Run the battery draw down test, just make sure everything is turned off or you will be chasing something that doesn't exist. Always check the glove box light if equipped.

2000 durango, same issue. Not sure why, but the power amp under the dash on the passenger side is so hot you can't hardly touch it. We've disconnected the power amp and that took care of the drain. We noticed two things, 1. Front speakers stopped working. 2. Battery was dead over night. Not sure why the amp is not turning off and why it is getting so hot, but its something to look at for people with this issue. Pull the plastic on the passenger side under the dash and see if your amp is hot. If it is, then for some reason its not turning off. Just haven't figured out why yet.
