Passenger side floor bottom flood

I don't know where to start.

1. Couple months ago, I heard water flowing under the passenger side and back floor, so I opened up and pour out the water and dried. (It rained during the week)


2. 3 days ago I had electrical issues with the car and I found out water was flowing under the passenger side and back floor again. (Rained during the week as well)
a) dashboard started to turn on and off.
b) I couldn't lock/unlock my car with key fob. Windows and sunroof did not work.
c) The car starts and I can drive it.

Any recommendation with the current symptom? It's a 2008 vehicle, no warranty.

Thank you.

Very respectfully,

Albert

I believe I’ve heard it mentioned that a plugged sunroof drain can cause that, but I have no first-hand experience.

Yep

It could be one of a few issues. I would check the sunroof drains, and I would also pay attention to the windshield area (near the headliner).

1). open your passenger door.
2). place one hand on the inside of the windshield, and the other hand on the outside of the windshield
3). push back and forth.
4). If you hear any popping noises, you need to reseal your windshield.

If you cannot say something helpful. Do not say it. Individuals come to this forum for help and not BS.

I would have the sunroof drain checked as well as ac condenser line. Agree with checking seal on windshield. Mercedes loves to put electronics under seats. A real mess when they get wet or you have a spill.
