Car has a new battery. We've checked all the fuses without the battery hooked up. Cannot find a drain. However, when hooking the battery back up the drivers side window started rolling down by itself and the CD player started making noise.

This sounds like you have a BCM that is not powering down into sleep mode. But to but sure here is a guide to help you go through the easy stuff first.

I checked it out and I had a CD stuck in the player once I removed it the problem went away. Thanks for the guide.
