Have you scanned it for DTC's? Not just PCM, but also BCM

It helps those who help you if you will include a complete scan of the vehicle with each help request.

These are really bad about water intrusion from plugged sunroof drains into the BCM causing this issue and many others. However I agree, some testing needs to be done. At least a code scan would be a great start.
