Water Puddle On Driver's Front Foot Area

[Dabman]

Hey guys, I'm at a loss here. There was a huge puddle of water after a rain storm where I put my feet as a driver. Let me say again, this is on the driver's side so please no comments on the passanger side crowl issue. The only thing I have noticed is the rubber on the car right before I step into the car is soaked compaired to the passanger side which is dry. I'm thinking it may be a plugged sunroof drain hose? Any ideas how I could check this? Any other Ideas?

I don't have a sunroof and I get water coming in from under the dash on both sides. I believe if the cowling drains are plugged under the windshield it can leak on either side can it not??? Mine seems too.

Is this the first time it happened?

Maybe you didn't close your door all the way.

Mine used to leak bad when I first bought the car and I took an aid compressor and blew high pressure air threw the drain hoses on the sun roof. That solved my problem. There's 4 of these hoses and you will have to take some of the interior apart to blow em out.

This is the second time it has happened.

To Marines542: I think I see the holes in the 4 corners when I open the sunroof, but where exactally did you access the drains to blow them clean?

To Bandid 1228: As I stated 3 times this is on the drivers side not the passanger's side

I had a long skinny air hose piece to blow the air. And I had most of the roof apart. So it was easy. I had the sun visors off, the over head light and rear view mirror off, the front and rear a pillar's off, the side pillars that the seat belts were on off, and o **** handles in the rear off. The ceiling as pretty much hanging down about a foot and I came from the bottom and cut the factory wire ties on the 4 drain hoses so I could pull em down and blow them out good then put it back up with new wire ties. I then took black silicone and coated all the old silicone that was degraded from time and heat. Since then no leaks

This post is for the passenger side for the cowl.

aren't the drains in the front door jam? (blow air back up to clear them)

theres the other one for the a/c condensate drain too low on the fire wall.

[DirtDog]

Yes I never took the time to see where the drains came out at as the original sunroof seal was leaking as well so I had to take everything apart for that anyways. I didn't know the AC had one...I'm gonna have to look for it myself cause I wanna check it while I'm at my other work on it Sunday

Hey Scotty, where exactally are the drains in the front door jam?

[Scottydoggs]

pretty sure ive seen rubber elbows coming out under the door hinge. or in the jam area.

found this link. worth a look if you dont see then in the door jam. Pontiac Repair: '04 grand prix sun roof, drain hoses, sun roofs



quote from link:

All sunroofs leak! under the roof there is a gutter to catch any that gets past the seal on the glass. If the drains are plugged up the water has no place to go.Also the drain hoses have a tendency to wiggle off the sunroof modules and then the water leaks out. Lastly on that year car the hoses for the sun roofs plug up at the bottom. If you pull off the trim panel on each side of the car under the dash board you will see the drain hoses tucked into the body. Pull out the hose and cut back the ends of the hoses from a flat cut to a 45 degree angle and stuff them back into where you found them There was a service bulletin on that to do that the ends lay up against the body and the water back up the tubes. When they are cut at an angle this will not happen. Good luck :}

Found this for whoever finds this thread Later.

Gonna look at everything more tomorrow and test my 4 drains.

[Dabman]

Hey guys, thought I would post a final update for whoever finds this.

So I tested the drains and found out that the passanger side was totally clogged somewhere in the hose. My guess is that it overloaded the driver's side causing the leak.

After trying to clear the clog with weed whacker line (Not successful) I found an old bike and used the brake line. Perfect!!!!

Although you can not get it totally through because of the 90 degree bend right before the hose exits into the door jam.

What ended up fixing my drainage problem was removing the drain hose from its attachment to the car body in the door jam.

I think there was a kink in the line at the 90 degree bend making it impossable to drain, so I just have it loose. Drains like a champ now.
