Water Pooling on Floor Boards

I had this problem and it was my windshield

 

What was the windshield doing?

The reason why I didn't suspect a leak like that is its soaking the carpet under the mat, with car washes and sitting in the rain there is no water coming in. Only when actually driving in water.

 

Ahh, ok. Fortunately I have weathertechs so the water just went onto the mats. Definitely look for a loose grommet.

 

Yep that's the plan, I plan to go in this weekend and seal everything that may look suspicious and hopefully I fix this problem.

 

I had the same problem when I first trimmed and massaged for 35s. When you remove the fender liners, there is a small holes which use to be covered by a plug or bolt and its now exposed. Pull your carpet back and shine a light through there and see if you can find it shining through the firewall. It was near the pinch welds. At least that was my problem.

 

That would make a lot of sense, Ill definitely give it a look when I tear into it this weekend.

 

So here's an update I stumbled on to today. It rained today in San Diego and I checked under my mat and a puddle had formed, the truck was sitting not be driven, But it was only on the passenger side... So the conclusion I have is I need to seal all grommets and all holes possible in the wheel wells and in the floor boards. Than after seal the windshield and the AC duct as well. Apparently I have multiple water issues... More to come as I look into these issues

 

ugh. sounds like a pain.

 

I would think if it was sitting its most likely the windshield.

 

This is the first time I've seen a puddle while sitting, I never suspected it was something like that because with car washes I don't find any water. So now that I have water while driving and while sitting I'm just gonna seal everything I see

 

The windshield has been a problem for others it wouldn't surprise me. The other thing I could see if you was driving but just sitting water has to be coming from The outer shell,not from the under body.

 

Once I seal the windshield, how am I supposed seal the AC duct? It's just an open hole and blocking it isn't really an option.. If it's the vent not closing I guess I could seal around it and clear any debri that might be in there

 

I'm not sure. I never heard of anyone that needed to do this. But I'm curious as to how and if its needed.

 

As for the windshield. Did you consult a windshield pro or just a diy fix. I think I would have it replaced under warranty or insurance by a pro. Its known to leak on some trucks on the lower seal and maybe hard to re seal.

 

I have to do some research on the duct, as for the windshield I'm gonna take a look this weekend and see if I can place some clear seal along the bottom. It would be hidden by the plastic vent on top. It just kinda makes me wonder why a car wash wouldn't make water come in but rain would...

 

Ya seems strange to me as well. I could see if you were driving and that being the difference.

 

That's what I assumed the first time when it only came in while driving but now it's Doing it too when sitting too... Got a lot of stuff to tear into I'll keep this post updated.

 

Here is the TSB, gonna check it out tomorrow.
