Since getting this car I have had an intermittent issue with wet carpet in the passenger front footwell.
Usually after a solid wet period the carpet would be soggy and some newspaper would be needed under the thick 'PROTON' rubber mat [I once had a 1.5 MPi = dealer mats ftw ]
Webbie searching threw up windscreen seal shrinkage or sunroof drains.
After watching Americans cleaning Toyo drain pipes, with 'weed wakka' string on Utoob, I thought I'd have a look-see...
*note - need dry sunny day / likely !!
Dry sunny morning today....
Took sill flash cover and lower carpet corner trim off.
Reached into void and my finger touched the roof drain plastic pipe... Somewhat alarmingly, it rattled & waved about and I'm sure it is meant to be long enough to be positioned loosely [through the sill section/hole] into the empty space below.
TUBE IS TOO SHORT!
I inserted the above, a polypipe insert, and only pushed it 1/4 way in - very tight fit luckily - and now the extended pipe end is stuck down and fully through the factory sill hole.
Pouring water into the sunroof drain tray and it's running out of the sill bottom...
I poured water into the Drivers side (never a problem) and that came out that sill too!
Will check over the next week or so.... Rainagain Sunday
