Need help with leak from behind dash...190e 16v - PeachParts Mercedes-Benz Forum

Hi all:
The alarm in my car started going off randomly so I pulled the passenger side carpet to unhook the factory alarm. I noticed that the passenger side floor board was wet. It looked like something was leaking from behind the dash, since the rubber pad under the glovebox and the dash on the passenger side was damp and cracking from too much moisture.

Could this be a heater core leak? If not, what could it be? I had my windshield replaced a while ago by professionals so I doubt it is that. Any help is greatly appreciated.

If it was a heater core leak, you would smell coolant. Turn the heater to max hot with fan on low and see if you notice any steam or coolant smell. Also, how is your coolant level?

I bet if you soak up some of this moisture with a white paper towel, aside from dirt you will find that it is just plain old water, probably from a windshield leak. You did state that the windshield was disturbed a while ago?

The windshield was replaced by safelite, but I have never noticed this problem before. If it were the heater core that is leaking, where does coolant usually accumulate?

If it is a coolant leak, it could be anywhere. Heater core, which is in the center console area behind the stereo. Possibly a line to/from the heater core. But again, I would verify that you are losing coolant. If you're not, then it can't be coolant.
