997 - Puddle in rear offside footwell
Discussion
ISFGB... bring her round Sunday afternoon and I can have a go at fixing if you like...
When the rainwater runs off the roof it drains internally and is diverted into an open plastic drain channel, from which it runs down into what is probably best decribed as a hopper - as opposed to a resevoir. From the bottom of the hopper there is a 10/12mm dia outlet which extends, via a tube - I think - down to another plastic outlet set into the internal rear wheel arch. This area of the wheel arch is covered by the plastic internal arch liner. Any water that overflows from the hopper - this better describes the item rather than resevoir - doesn't run onto the surface of the carpet, but behind it where it then soaks into the 50mm thick dense foam backing to the carpet. Even with a good 10mm of water in the foot wells you won't feel the carpet damp.This really is a simple DIY job - the hardest part is getting the large rear wheels back on! There are just three washered nuts holding the plastic liner in place but it will not come out without removing the wheel.
And
A small plastic drain tray runs along the side wall behind the inner upholstery panel beside each back seat. A right angle fitting leads from the low point, sideways through the inner body panel and into the void ahead of the rear tire. If you remove the rear wheel, then the forward side wheel well liner, all you see is the metal body panel right behind it.
Almost at the bottom of the body panel is the outlet for the drain tube. The outlet itself is a simple plastic check valve with a rubber flapper valve about the size of a nickel. Therein lies the problem. The rubber was stiff with age, and gummed up about 90% with the same kind of crud you clean out of your gutters ... fine, wet, black gunk. When my car was out in the pouring rain at the airport for 2 days, the 10% drain capacity left was clearly not enough to handle the water flow, and a gallon or so ended up in my back seat floor.
I pulled the flapper off, blew out the drain with air, then soaked the flapper in Lexol conditioner to soften it before reinstalling. Considered leaving the rubber flapper off, but was afraid that road debris might come in the other way to block it. Going to pull the driver's side wheel and liner tomorrow.
