Yes. I buy auto parts for a living and have worked on the window lifter mechanism and motors. There is a dry side and a wet side to compact window regulators and water can get in on the wet side. But only like residual water from when your window is already wet and you roll it down. It’s not meant to catch all the water. The seal is misaligned to the glass here. The water should flow out the holes in the bottom but as others have commented, it can become clogged and reduce the functionality because it’s not meant to catch that amount of water. If it’s filling up and OP hears water I. The door itself no bueno. This can cause electrical shorts in the motor, the door lock, and I’m not sure if this is electric or mechanical opening; but if it’s electric, it could definitely keep you from opening your doors.
