#40 of 48 Re: WATER LEAK [bigskidogg] by jamijan Apr 13, 2008 (5:07 am)
Replying to: bigskidogg (Apr 09, 2008 1:43 am) Thanks bigskidogg. I found the drain on plugged it and the problem is sloved. I found the drain looking in from the top. In my 2001 Grand Prix under the dash on the passenger side, I had removed the cover over the blower, held in place by three anchors. I followed the pipe coming out of the blower into the firewall. Then I looked under the hood where this pipe should come out. There was the drain. a short elbow coming out and pointing down. It was difficult to reach but I was able to unplug it with a piece of stiff wire. My car has been dry since then. Thanks.

I have an 04 Grand Prix and lately I have noticed that whenever I get home from work or a drive anywhere, there is a nice puddle of water underneath the car where the A/C would normally drain out, except I haven't used the A/C. I've actually had the heater on. The puddle keeps getting bigger and bigger each time. This morning when I started the car and left for work, there was already a puddle of water in the driveway after the car running for only maybe 5 minutes. I popped the hood last night and found the water was coming out of a drain elbow that looks like it's going into the firewall. Why is my car leaking so much water on the ground???? I've never had this happen with any other car I've owned.

It doesn't get any better in 2006, my back passenger side foot well is a nice puddle and my car stinks like mold. Living in Florida, I can rest assured there is mold all over the car and it is now a health hazard. I would like to know why, if this has been an ongoing problem, hasn't GM done anything about it?

Replying to: jlgifford (Jul 12, 2008 9:48 am) GM doesn't do anything about it because people are still buying it. Seems like lack of dilligence on their end as a means of cost saving. They're actually saving at the cost of their customers.

Replying to: jlgifford (Jul 12, 2008 9:48 am) I have a 2004 Grand Prix and, like all of you, my passenger side floors and air conditioner have water leaking problems. My car also smells like mold and has since i bought it. When i speed up or go over a speed bump I can hear water sloshing around in engine/dashboard. The air-conditioned air smells terrible. I got my windshield fixed over a year ago and since then, the water leak on the floor has been minimal, but the air conditioner problem is bad. I'm taking it to the dealer tomorrow after reading this thread Replies to this message: larryboh (Dec 06, 2008 7:29 pm) dtrombley (Dec 08, 2008 1:16 pm) ralka (Dec 13, 2008 9:56 pm)

Replying to: rjcoyne (Sep 22, 2008 6:13 pm) I have a Grnd Prix that is doing exactly the same thing. Wet floor on the passenger side and a very annoying sloshing sound in engine/dashboard. Were you able to get your car fixed and if so can you share what was wrong? Replies to this message: dtrombley (Dec 08, 2008 1:16 pm) ralka (Dec 13, 2008 9:56 pm)
