The red arrow is pointing to the unknown box, the box is grounded to the car, has a small speaker or mic coming out of it, and four wires going from the box to the back of the car.










This hose was disconnect so I reconnected it. My driver side of the car was wet because of this unconnected hose. What is it?


Passenger side with the ML Amp is fine

 

nevermind it's just my rear parking sensors

 

If under your driver seat is wet, there's a good chance your HVAC system backed up. There was a TSB for this, but its actually not hard to perform yourself if your out of warranty. The only bad thing is that if you can already see your carpet being wet, then you probably have mold underneath it.

 

Thank you. I just checked under my driver seat and my carpet is dry and perfectly clean. I'll investigate further tomorrow. I also have ML like you, a few months ago my radio and DVD went dead but my AUX is still fine, weird.

 

most likely its your sunroof drain tube
