Where is the water coming from? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

jtminton · 06-09-2005, 04:50 PM

On my truck, whenever it rains or gets washed, I get water (not standing water, just wetness) on the floor where the kickpanels meet the floor in front of the doors. As a result, I have holes rusted through the kickpanels. I am guessing that somewhere there are some drain holes that are clogged from years of neglect. Any ideas where to start to look to either:

A) seal up the source of the water, or
B) open up wherever the water is supposed to drain?

Thanks!

Probably have a small leak around the windshield that lets water in. Check around the windshield for any wetness during and after washing your truck.

Your vents on the kick panels are not open are they?

I probably do (judging from the drips I get from the top corners when it rains really hard), but this also happened when I was wet sanding my hood. I just had the water trickling on the hood, so it never went up high enough up the cowl to get to the seal.

On mine, the sealer that sits in the drip rail had dried up and chipped out allowing water to make its way between the layers, down the pillar, and through the kick panel vent.

Got rust holes on the kick panel.....

The one on the driver's side usually is open, but the one on the passenger side is always closed (at least right now) because I A/C, but I have the controls taken out of the dash, so no vacuum.

Well if water gets into the lower windshield it can leak onto the dash and down the drainholes in the dash to the floor around the kickpanels of the truck. Maybe you have a hole in the cowl area and its leaking through there onto the floor?

Well, my drip rails have certainly seen better days. Can I just run a thin bead of silicone or something in them to reseal them, or is there something that would work better?

take a look at the antenna seal ...where the wire comes into the cab

*rickspickuppart* · 06-09-2005, 06:05 PM

simple fix - pull the cowl chip out the sealer where the firewall meets the cab (on top corners on both sides) and fill them w/ some type of sealer. we fix lots of them after every rain storm and that is the problem about 99% of the time. Even if it looks like it is fine dig the old stuff out and fill it up w/ sealer because it never looks bad but usually is.

you got a good pic of the exact location shawn ..... ??

*rickspickuppart* · 06-09-2005, 06:31 PM

nope, I don't have any trucks w/ out cowls on them, but if you take yours off you will see what I am talking about it's pretty easy to find

Don't use silicone! paint will never stick to it. Get some auto body and seam sealer. It looks like white calking but it's made to seal of seams in your body plus it's paintable. My drip rails were the same way and I used a wire brush on a drill and got all the old stuff out. Then I went back with a bead of the seam sealer and smoothed it out with my finger to make sure it got into all the open areas. You should be able to find it at some auto parts stores or paint and body supply stores. It's not expensive (less than $10 for a calk gun tube)

I have a window seal leak and it comes in on the dash at the corners. So as you can see by the previous post tends to come in from any number of locations. Good luck on your search.

Later,
Aaron

Any chance it could be leaking around a poorly sealed rear window, then travelling forward along the edge of the floor? I have had that happen...

My 70 leaks somewhere around the bottom of the windshield too. Now I know
what to look for. Thanks for the info guys!

I have a Blazer that is completely disassembled so I figured I would snap a couple of shots to show what I THINK Shawn is talking about.

Mine is also leaking there. I had forgot about those two filled joints. Doesn't the windshield need to be pulled to clean them out and refill the seams?
