Water standing in rear floor board

[chevygirl_2004]

Hey guys, I know i have seen posts about this before. Just read one about water in the front floor board but I'm not sure if the solution would work for the rear. We have been having heavy rains here. When I looked in the back seat the other day on the passenger side there was water standing in the floor board. I couldnt see where any had been running in. I saw on another post that the person cut a whole in the bend of the weather stripping and put a drain tube in there. Think that will work for the back passenger side????? Thanks in advance for any advise

can you see the rubber seal that seals the door and see if it's in place or waren off? or the seal around the side window roll window down and pull in and out on window if it wiggles that rubbers waren. i lnow this going to sound stupid but can you have someone get in there while you spray it with a hose? unless it's raing hard enough can you get in and see where it is coming from because you need it fixed if your keeping car? or the floor boards will rust out.

yes there is drain tubes behind front wheels and in back there in the front of the of the back wheels you can try cleaning them.if it don't go with what you found probably in buick forums dreal holes.

In general (not PA specific) water on the floor rarely comes through bad door sealings. It most often comes a long way, from windshield sealing, rear sealing or sunroof....
Such a leak can be hard to find, and you may see that parking the car in another direction could even cause leaking to stop. (you probably have it parked with the nose at the highest point, try the opposite and see what happens..)

or maybe in a garage...

I have noticed that there is a lot of moisture on the inside of the windshield. I was thinking of resealing it or just installing a new one. Sounds like if its coming from anywhere it may be coming from there. I will check the drain tubes and the weatherstrip.

If you have moisture under the carpet inside the car, you'll have moisture show up on the inside of the windshield and other cold areas through condensation.

It sounds like you have a sunroof and the drains for those on some models have given trouble--the front drains come to mind, where they break inside the car and leak.

Also you may have water coming in around the side windows. Water goes inside the door metal around the seals normally. It is kept from coming to the inside metal panel of the door by a plastic layer that is caulked to the door frame with low spots in the caulking that guide the water to drain holes directing it back to the interior of the door and to the drip holes on the bottom of the door. The caulk hardens and lets go; so the water can drip on down in the inside metal of the door (under the pretty inner layer we see when sitting in the car) and then drips at the bottom onto the door sill and down into the carpet.

To check someone has to run water with a garden hose around the window of the door for a time. Then you check the interior perimeter of the door around the inside cover for water tracks or wet trails of water. Because it's specific to water hitting the window and falling down into the door, it may only occur when the rain blows against that side of the car; other times the rain is hitting the opposite side, so no new leaking occurs.

If you're in a cold climate, leaving the windows down an inch or less will let dry winter air blow through and will evaporate a lot of the water from the carpet. If you park inside a garage, just leave the windows completely down. You can even set up a fan to blow air into that part of the carpet. I wouldn't panic about moisture collecting on the windshield indicating a leaking windshield without more symptoms.
