When trying to find the source of water on my passenger side floor board in my 2008 Honda Ridgeline I found a loose part under the dash near the passenger door. It has a Honda part number 1W6K-0. My searches of the part number come up empty and I was hoping that someone can identify it and tell me if it has something to do with the water on the floor. It has to be there for a reason.

Do all the doors in the HVAC unit work? Call Honda with the part number.

 

welcome to the forum. 1w6k-8 is not a honda part number. may be an after market part number. Sorry could not find it. Do as grcauto states to take it to Honda dealership to find out what it is. If you're adding antifreeze to your radiator, it may be your heater core leaking on to your passenger floor. Also it should smell like anti-freeze in the cabin.
