1/ It was mentioned in another thread that water gets behind the quarter light seals and leaks into the sponge filled area. This would lead to the sponge holding water and sagging down to the bottom where it may block some sort of weep hole (or maybe Toyota didn't expect water to get in here - hence the sponge inclusion). Now I have no idea about this as the base of mine was rusted. There could have been a hole, but it could also have just been a corrosion void.
Regardless of removing the sponge, if water gets down there because of ageing seals (which we all now have) then we need to know if there should be a hole to drain water into the lower sill?
2/ Where are the drainage tubes for the roof gutters? Surely they wouldn't go into the foam filled space as that would be a real design mistake?
If anyone has removed their foam and has nice clean sills (stick your phone in, turn the flash on and post up a pic) that would be a huge help!
Cheers
