The vehicle listed above has had water damage due to sunroof drains not draining properly. With that being fixed it has caused problems in the front of the vehicle. The heat in the front of the car isn't working but the back works perfectly, the windshield wipers only work with a right turn and the power to the radio comes on just no sound.

Yep, it sounds like the BCM got wet, here is the location so you can dry it out and it might start working again, if not you will need to replace it. As you can see it is right in line with the sunroof leak. If letting it dry out doesn't work, you can search Google or eBay for a preprogrammed rebuilt unit. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.
