(2004 chevy impal ls)Both rear floor panels completly soaked everytime it rains!I laid 2 paper towels on top of my rear floor mats,both sides are getting wet from underneath the mats.Leak is not visable,and the divider(hump)in the middle is completly dry!one side is always wetter than the other.Sat in the car last time it rained,and was unable to tell where the leak was.has anyone had a similiar problem like this?or was there ever a recall?I have a sunroof,but there is no leak,all seats are dry,roof, glass,and headliner bone dry.Please help?

Sounds like the door gasket or trunk gasket is not sealing.
You may have to take it to a body shop to find the problem.

there should be drain holes that lets the water drain out check for them their most likely clogged

Hi,

This is of concern.....especially if no recent rain.

Your vehicle is covered by warranty and should be checked by your local BMW dealership.

If there has not been any rain, but your floor is wet....it's possible your heater radiator core (radiator) under the dash, is leaking.

Seek immediate attention.

Cheers,

did you drive in the rain before and this not happen. if you used the heater,or defrost,then sounds like heater core is leaking.

There is a great possibilty that there is a leak on the Left Side of the Windshield. It is most likely in the area of the upper left side.
The reason for this conclusion is:
The rain water is coming in the Left Upper Side; and either coming down the "A" Pillar, or traveling underneath the trim on the inside roof and coming down the "B" Pillar.
The only other explanantion is a torn, worn, cracked or dislocated Weather Seal on one or both of the doors, allowing rain water to come in. Inspect very carefully these Weather Seals, especially on the top front portion of the rear door.
To help you locate these after a hard rain:
Take the trim panels off the "A: and "B" Pillars and the Roof Line above both Doors. Check for wetness underneath the trim. Or take these trim panels off, and place folded paper towels under the trim panels; reattach the trim panels and wait until it rains. Afterwhich, take these trim panel off and check the paper towels for wetness.
The Windshield Seal is easily inspected for cracks and tears.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

I would say you have either a bad seal on the windshield or the seal on the passenger door opening.

Is it raining wherever you are?

Look I had the same trouble. What i did was take out the seats, Remove the carpet. dry out all the water with a few old towels. After you dry it out. Put a fan on it. use a hose or go out in the rain and look for leaks. its a door seal or a window seal. fix the leak and test one more time. clean the rust off and paint with rust killing paint. Clean the carpet while its out with a house shampoo machine.
hope i was helpfull

i would check water in radiator as sounds like the heater box under the dash is leaking and will certainly end up on floor

Have you by any chance jacked up the passenger side, or got vehicle on a hoist to make sure there isn't any plugs on the underside that may have fell out? They could be round or oval metal or rubber plugs, probably in that area.
