Default Re: Moisture Behind Driver's Seat

I see all the HVAC unit being on the passenger side. The AC vent hose exits above the transmission on the passenger side. Everything is beside the centre radio console, so climbing the transmission hump would be hard.

A couple of weeks back, I found moisture in the DS footwell. I thought it might be related to the fact that I removed the OEM dead pedal and installed a M-B dead pedal using double-sided, industrial grade Velcro. But thought it strange as I've had the M-B dead pedal in the car for 2-3 years w/o any issue. Anyway, I soaked up the moisture, which was only at the bottom of the dead pedal, & re-installed the OEM version. No moisture since in the DS footwell. I even checked this morning again to see if the issue I'm having under & behind the seat is somehow related to the moisture I found at the base of the dead pedal. But the dead pedal area is dry.


All my experiences with water leaks (roofs, cars, anything) is that until you find the entrance point, you can go crazy with assumptions. Water leaking into a frame of the dash or parts inside, can travel over to a place you would not have guessed. I have seen roofers rip roofs apart trying to locate a leak in (say) the kitchen, but would up from a dining room and it slowly ran down (through capillary action) rafters or such. Hard to know until you get in there and find it. There is available a dye that is used for leaks, unseen until a black light is used. Mix a bottle (or two, might take a while), and have access inside as many access points you can find. Start on one external area, pour, wait a few hours/days (documenting where and when) and keep going until your satisfied the black light has found the dye. It will take time, unless it is very obvious right off the bat (example, first place you poured the dye laced water). You have to find it because the water will 'wick' up into and through wiring, causing corrosion as a minimum (luck comes in here that it doesn't make it to a module or three). Good luck, your going to need it!
