Mystery! - Cab leak on driver's side

First post. I searched the forums and discovered a similar thread on the 2nd Gen forum (Wet floorboards).

I'm getting water in the cab after a rain. Parked, not driving. The water is showing up on the driver's side. I have done a bit of research and I see that there were some TSBs about leaks for the 1st gen, but I don't know if any of these are pertinent.

Anyone experienced this problem and then fixed it?

Thanks.

 

personally, NO. but on the work order history for my '08, the previous owner had the weather seal replaces around the door I believe due to a leak.

 

Weatherstrip looks pretty good. I don't think it's coming in there. Does anyone have access to TSBs for the 1st gen? I would be interested to see what this issue was.

 

Exactly where is the moisture appearing?

 

It looks like it is hitting near the little plastic footrest on the left near the driver's door. In other words, it almost gives the impression that it might be coming in from under the dash. But it is definitely not coolant.

 

I would take the door panels off to make sure the clear plastic liner is sealed around the doors. Maybe previous owner installed aftermarket door speakers and permanently removed them.

 

maybe a windsheild leak.it can be coming in from the door or ws,unless you have a hole in your roof?

 

I might be the windshield or something around the cowl. I've read the 2nd gen stuff about the 2005. No aftermarket speakers.

 

My first guess would be a windshield seal leaking or water getting in through the firewall around one of the openings. It might also be a pinhole leak from the wheel well.

 

I have the exact same problem. I have found the TSB on this but it is only covered under warranty. I am really bummed out about mine. I live in south Texas so we doin't get a bunch of rain but when we do it gets soaked. I am gonna try some silicon around the rubber boot that Jimig mentioned because I too have a few wires going through there. As I type....my windows are open and the carpet pulled back in order for it to dry. I have 100000 miles on mine but it still looks new. Can't stand to think about a rusty floorboard or anything of the like. Please let me know if you come up with a fix. I have the same issue.

 

I would say you sit in the cab with the door shut and have someone else outside slowly pour a bucket of water by the door, windshield and wherever else you think it might be coming from and see if you can tell. Sounds like you have a major leak so you might be able to find it this way. Thats what I would do.

 

this is it. It happened to me a couple weeks back. I ran a bead of clear silicone around it and now im good

 

I replaced all the rubber on the drivers side door and put silicone around and on everything on the firewall. I believe if I use just a little more I could float across the river. It still leaks. Gonna take the fender off next I guess after I try to run the water hose over the top of the cab to see if I can see the leak.
