Dreaded Wet Floor Syndrom

Hello folks,

My 1993 L300 has the dreaded wet floor syndrome in the drivers side foot well. I've done a search on here and found a great old post from Morganizer on how to repair this with great photos included. It's described as a nasty job, primarily because there are a few screws partially hidden under the windshield rubber that are most likely rusted and will be stubborn to remove.

I'm mechanically declined at the best of times, and I dislike jobs that are difficult. I have a friend who owns an auto glass business and is excellent at what he does. My windshield has a few small pits in it, and I'm wondering if this might be the time to change the windshield and rubber while also addressing the corner pillar leak at the same time. Those nasty screws will be completely exposed with having removed the windshield right?

Not sure how readily available windshields are for our vehicles, although my buddy says he can get any windshield for any vehicle. I'm guessing it would be the same for the rubber gasket....

Anyway, if anyone has any thoughts on this, or has recently tackled this job and would like to offer some advice, I'm all ears:) As it stands now, my fuses are getting soaked after a decent rainfall. The overall condition of my van is excellent with only 135 kms on the clock. I'd hate to ruin things prematurely by not keeping up with the known maintenance that's required on these older vehicles.

All help, advice, support, well wishes etc are most appreciated:)

Cheers, Phil

You should be able to source a window for a Mitsubishi "Van" or "Wagon" which was the 2wd L300 for the U.S. market ('87-'90).

Those screws under the window seal do not have to be removed; they only need loosened a couple of turns. The corner panels are slotted to slide out from under those screws.

It's safest to remove the windscreen, those screws can be bastards and it's easy to slip with the screwdriver/vise-grip/blowtorch and break the windscreen.

There's a post in the TRL regarding footwell leaks: there are a few places water can come in. http://www.delica.ca/forum/viewtopic.php?f=99&t=9793


Any chance you could post a link to Morganiser's leak fix thread? I'll add it to the TRL as well.

Does anyone know the diameter of those screws just in case someone did eventually grind them off which I am probably going to do...... because they will not budge.... at all.

They're just 8-gauge self-tapping sheet metal screws with a button head. Nothing fancy. From memory I replaced mine with stainless.

Thanks for the advise folks. I guess I'll most likely remove the windshield to do this fix. I'm going to see if my buddy can first source the glass, then I'll with the local Mitsu dealer if he can't get me a windshield. Not sure about the rubber gasket. I'll find that great link from morganizer and post it on here. There are a few good links actually. And while there are many possibilities as to where the water could be coming in from, I'm certain that on my van it's due to this seam on the corner panel being compromised. Stay tuned folks.....

Cheers, Phil
