Find out which one fails first (which window, or trunk or sunroof). Probably it is a defective module. It is a signaling issue due to bad module (usually a door control module inside a door, when it gets wet).

You need to remove the door molding (inside panel). Also, please make sure you do not have any wetness under the passenger footwell carpet. There is a connector which causes problems like yours when it gets wet. Make sure you do not have any wetness where the battery is (under the rear seat). There is a module called PSE which is mounted on the base of the well, and when it gets wet it causes similar problems.

No, you need to remove the connectors and spray some electronic contact cleaner, let them completely dry and re-connect. Then disconnect battery and reconnect as you did before. If this does not help, maybe a module is bad, and you need to identify the one failing with a scanner that can scan the body control module faults. There are recent posts with problems similar to yours in W210 threads. Search for them (one of them is from Okie-Benz).
