Allow me, if you will, to tell you an epic tale. One of triumph and misery, of persistence and frustration. The story centers around a mystical fountain of youth, in that the fountain is a godforsaken water leak and the youth is what I lost trying to track down the stupid thing. :grumpy: Bear with me, word fort coming.
A year ago I noticed that my drivers front carpet and floormat were wet after a heavy rain. I dried the carpet and forgot about it until the next time we had slight rain. Once again, the floormat was soaked through and the carpet beneath it was damp.
I water tested the entire windshield area, thinking that it was getting past the windshield and running down the firewall or dripping off the dash and onto the floormat. After about an hour of being tied into a pretzel, laying upside down under dash with the blood rushing to my head, I noticed water beginning to gather under the LF door. I popped the door panel and it looked like it was coming through the bottom of the vapor barrier. I resealed both front doors and called it a day.
Again, I noticed water leaks on the front carpet and floormats, now on both sides after it rains. It seems to only leak on whatever side is facing up my slightly sloped driveway.
In an extreme fit of rage, I called my Toyota dealer and politely requested a couple new vapor barriers and a roll of fresh butyl sealer. I removed all of the old butyl tape and applied fresh tape. I applied butyl tape to the back of the speaker to seal it to the door. I cut pieces of the old vapor barrier and double gasketed all of the holes for the lower door panel clips, from the inside of the door. I carefully arranged the wiring harness through the door so that any water that drips down would run back inside the center of the door and away from the interior. I double gasketed this area too, and even sealed it again with gorilla tape over butyl sealer. There was no way in hell this was going to leak in anything less than a tide from Moses himself!
Blasted! The next time it rained... the RF carpet was wet. Again. I flipped the truck around and let it sit for a month. I went out today, jumped in and promptly slid on a sheet of ice. Should've worn some ice skates. Note to self, pick up ice skates for the commute to work on Monday.
So, wonderful Tacoma World, I come to you hat in hand to ask... WHAT IN THE HELL IS GOING ON HERE? It's too damn cold to water test, but I would still guess that it's the <expletive> vapor barriers. Could my door seals be leaking even though they look ok and there's no wind noise? Is Toyota trying to punk me into buying a new truck? Is this possibly a known issue that everyone has run into and there's a Sticky at the top of this forum that I could have found with a simple 30 second search? Please oh please help me figure this out before I take my shotgun and make a few extra drain holes in the floor pan.
