This light has come on a few times, typically after being in wet weather. Happened to me today on my way home, been raining all day. Nothing on the seats, no windows left open for things to get wet. Any ideas of how to track down the culprit?
Where are these sensors located? Or maybe the plugs for them. I am thinking something is getting wet but I don't know where to look.

 

GD3 Fit doors (both front and back) can allow water to enter under the inner panel. Check the carpets under the floor mats.


There are several Topics about this and one recall (on the Drivers side). Search for Wet Carpets or the like.


The sensors are INSIDE the seats. If you have mats make sure that the RH mat hasn't slipped up under the seats. (Factory mat kits included a hook to prevent this from happening.)

 

I checked the carpet yesterday, wasn't wet at all. Floormats are definitely not stuffed under the seats.
Maybe I'll just rip out all the door panels this weekend and see whats going on back there. I need to put my new fabric on the inserts anyway.

 

Light has been on for a couple days now (lots of rain here in fl). Pulled into the parking lot at work and opened the passenger door, light went off. I closed the door and the light came back on. Opened door, took a couple seconds but light went off.
