2007 Kia Sedona question

My wife has a 2007 Kia Sedona ex… All of a sudden it has a bunch of electrical gremlins, such as sometimes if you turn the head lights off the passenger window opens and your cant close it until, you turn the lights back on… Problems with the d-side power seat, the power mirrors, ect… The only thing I can think of that all three have in common is the BCM… Where is it located on this van??

This seems to have all started when a drive through attendant spilled soda on my wife and her door by accident… I have had the door panel off and cleaned it all up, so I don’t think it’s the issue any more.

Thanks in advance for any help you can give !!!
