Water leak on passenger side fr& back,under the carpet was over 10 gallons of water

My freind was at my shop today with an 05 impala,when I went to clean and detail his car I noticed that the fr & rear under the carpet was floating in water, i took off the moldings and the back seat,pulled up the carpet and both the fr &rear floor pans were floating in water, she has a bad leak somewhere, anyone else ever had this problem?, I took the hose and started to spray water around the top of the fr glass and there was not much of a leak so I soaked the glass down where the plastic piece for the wiper covers that goes over the end or bottom of the windsheild and the water was coming inside the car by the blower motor,I took the clips off to get the plastic peice off and the cabin filter was wet and I could see the blower motor,that plastic piece that fits on on the bottom of the windsheid is warped and not sealed to the glass and the water is going down through that ,into the cabin filter to the blower motor and letting in the water to the inside, thats the only thing I can see,it looks like the plastic is suppose to fit snugly onto the glass but looks un even and lets in the water, anyone have any more suggestions before I get him to go to the garage and get this piece replaced, she has warranty on her, thanks.

Here we go again...

There are a few possible causes for this -- the most common is poor blower case drainage --I would suggest that as soon as possible, get under the dash and remove the blower motor -- it's really easy, three sscrews and it drops right out -- you'll find that it will be wet and probably rusted -- Then in the opening, find out why the water is not leaving the drain in there -- one big problem is that there is cooling hose that directly enters the blower motor armature brushes, if water enters here, the blower motor is not long for this world -- the fan speed (blower motor) resistor pack is also in this water path, and it will also short out, leaving you only high-speed fan operation.

You have to feel around to kind of check for stuff in the drainage areas -- then try to run a coat hangar or something through the drain hoses that exit in the fendewell door opening. Ideally, you want the stuff to dislodge out, but it may just go back into the case -- so that's why removing the blower motor helps.

Also, if you look up into the case, you should see a filter -- the cabin filter -- this should be there, if it's missing or looks bad, it can be replaced from the top.

G.m can't find the leak, all the rubber seals, strip, is all in place under the plastic where the cover is over the pass side window, she is leaking down the blower motor, anyone else havve a suggestion to repair this problem

Yep.

Yep.




If you don't read whats offered to you, we can't help.It was the rubber strip under the plastic wiper cover was not sealing good enough so they epoxyed it on and the leak is gone, another mech had a closer look and found the prblem,thanks to you who replied.

Is it me or is this seal the problem 9 out of 10 times?

I bought my '03 used from a dealer. They replaced the passenger compartment filter before I bought it. The first rain after my purchase, easily 3 gallons of waters in the front. I hopped on here, found all of the possible reasons and started to deduct all of options. Then when I called the dealer I bought it from and told them I wanted them to clean the water and carpet and repair the issue. They told me their "leak guy" had to look at it and determine the cause. Plus they wouldn't clean it or give me a loaner for the hours they had my car. So, I said forget them, got some marine caulk from Auto Zone, replaced and caulked the seal and have not had a problem since.

I JUST WANT TO THANK EVERYONE WHO CONTRIBUTES TO THIS SITE. ALL OF YOUR INPUT IS EXCELLENT AND HAS HELPED ME WITH ALL OF MY VEHICLES FOR THE PAST FEW YEARS.

I had this problem as well. Now my Fan Motor is ruined. I have fixed the leak, a little late for my fan. Is it difficult to change the fan motor? I can see it from under the dashboard. Also, would this cause the radio to stop playing? It still turns on but produces no sound.

Thank you

Thank youyou probaly have a broken wire inthe back pass side under the carpet in the wiring harness, just fixed my problem today,where the floor was wet it has some of your wires corroded, take up you carpet in the back right hand side,pull the wires out of the harness and look for the orang wires,they are the power wires for your stereo, look for the orange wire which has a 2 inone like a fusible link type,pull on it to see if it is broke, more then likely it is,just cut the wires and put a new one in to join it back remember to put the wires back together with the 2 orange ones together into the other orange wire like a 2 in one, this will make your stereo work again, while your at it check all of them to make sure they are all good, when your finished retape all the wires with black take to prevent anymore water getting in there to rust them out.

i cant -$#@ing believe this I knew about this passenger leak issue but it has never happened to me. This morning after getting in my car i found the passenger side was flooded unfortunately i placed my bookbag there and 2 brand new books are ruined ($220). It gave no warning just flooded all at once. .......................:@( If my notebook computer were there this car would of been up for sale.

The same thing happened to my car last week. My lighter does not work(when i push it in it just stays in unless i pull it out and does not pop out and doesnt heat up either) and also the light behind the right temp. switch is out. These problems were happening before the leak in my car i just never got the chance to get it looked at. Do you think those problems are related to the leak? And around how much should i be looking to get these all fixed. I have a 04 impala.

i called the dealer to schedule an appointment and right off the back he said 125 - 150 to fix it. They havnt even looked at the car yet and what if it is something simple such as a seal? Do yall think i should take it somewhere else?

Do yall think i should take it somewhere else?definatly, just take the plastic piece of the bottom of the right side wiper arm, very simple,when you get that off there is a rubber strip about 4-6 inches long,it might be off or just not sealing properly,take it off and put anylind of silicone on to seal it properly,that will fix it, then check under your carpet pass side fr&back, if full of water take off you door sill molding, take out the pass seat, 2 bolts in the back lift and tilt out, get something like some sticks off wood to hold up the carpet and squeeze as much water out you can,then shop vac it out, I left my up to dry for about 3-4 days

Thanks for the response. The black weather stripping had fell off just like yall said. I also checked under my carpet, it was only a lil damp so i used a towel to clean that up. The lighter was just a broken fuse. The only thing that still doesnt work now is 1 of the climate control knobs. It works fine but it doesnt light up at night(the left knob lights up though). Could this be another fuse or do you think a wire may have been shortened out.

Does anyone have a photo of this rubber seal under the wiper cowl??

I just had the exact same thing happen to my car... About 1 inch of water on the passenger side floor... And just recently I cleaned out the leaves and stuff from around the cabin filter... I don't remember seeing any other rubber seals in that area... So if anyone has a photo of the seal it would be helpful to me...

Thanks...

Sorry to revive an old topic. I just had the same issue with my 04 Impala and the dealership will not help out even though it was purchased less than 3 months ago.
When I pulled apart the cowl the rubber seal was completely off, just wondering if the seal attaches to the bottom of the windshield or to the body just below it?

Thanks in advance for any replies.

I just ran into this exact issue. Posted on the other listing but this is it to the T.
Not at home to check for the fix but I looked at the wiper area before. Do I lift the screen area. I dont understand the exact location of the gasket.
Gettinf ready to get hit with Tropical Storm Fay in Fl.

Just performed the task. About 15min. Had to figure a few things out first.
All form passenger side.
Best todo is turn on your wipers and turn off key when wipers are straight up.(gives easier workng area)
Next remove big looking screw..unscrews just like screw. Next there is 2 pop up clips. Need smaller screw drive to pop up inner portion of hold down clip. then remove the whole clip.(2 of these)
now you should be able to pull up on the shroud. My seal was just laying right there. It is about 1.5ft long. I saw a few post of 6" You can see it the molding is not in its place the rain water will run right into the air filter into the blower housing area then into your interior.
I siliconed the rubber seal back into place and reassembled. Hopefull all is well.

This was done on a 2001 Impala. Getting ready for Tropical storm Fay in Florida.

I had the same problem with my car, I found the seal under the cowl was half way off causing water to leak into the carpet. After fixing the seal by siliconing the attachment points, I highly recommend removing both front seats, console (if applicable), rear seat, and finally the entire carpet. Unfortunately if this was just a layer of carpet you wouldn't have to do all this but underneath this particular carpet is about three to four inches of sound deadening foam which soaks up the water like a sponge. I wasn't able to wring out the water so I hung the entire carpet from a wire in my basement and let it drain by gravity. I accelerated the process by running a dehumidifier next to it. Even then it took about three days before the carpet was completely dried out.

Another thing to note is that typically people wash their cars using the auto wash, this in turn I have found saturates the carpet if you have the faulty seal.
