Hidden Leak

frieserh · April 7, 2008

I have a 2000 GMC Sierra. I got the windshield replaced in January (I live in Ohio) and everything seemed to be working well thought he winter season. This spring I noticed that my passenger side floor was soaking wet after two days of heavy rains. I removed my passenger seat, and back seat, and lifted up the carpet to let it all dry, and try to find the source of the problem. Obviously I have not found it yet! The carpet is still up, so I can soak up the water that runs in. It only happens when it rains, it does not seem to be related using the A/C or Heat. The car will be parked outside over night, and if it rains, there will be a large amount of water on the floor after a rain in the morning (only passenger side by the door jam). I physically check the door seals and they look to be in good shape. Any ideas on what the problem could be? If so how do I go about fixing it?

Have you tried using a water hose to determine where it's leaking?

They did not install the windshield correctly; have it redone.

I hosed the truck down last night, to try to recreate the leak and I had no luck. I spent 15 minutes trying to find the leak and could not. I also turned the heat on full blast, and washed the windshield to see if any bubble form. No luck with that either. Any other suggestions?

what he said, as youre running the water (have it runnin onto the roof from the back and runnin forward) press on the plactic or rubber moulding around the glass, and on the top edge gently lift the lil roof side flap if it has the rubber trim.

I have a late model 1999 Z71. Had the same problem. Replaced the windshiled twice, ran the heater (even took it to a AC shop), numerous hose downs with the garden hose for 15 to 20 minutes at a time. Could not find the leak! But every time it rained, the passenger side carpet and floor was wet. This went on for about 6 months. It wasn't until last week that I stumbled across the root cause. I noticed that when the carpet and floor trim is pulled back there is a track that the wireway sits in. This wire way is covered by the step guards. All this is located right next to your door seal. I noticed that the forward section of the track was full of water. The contour of the track naturally gravitates the water foward casing it to wet the passenger floor board. Most of the water was coming in around the contoured section of the door where the seal and door appeared be in good contact. The water would fill up the wire-way track and over flow into the passenger side floor. I took my truck to the local body shop and had them adjust the door. I have not had another issue with water enetering the truck since then. I know this worked as it has rained the last three days in a row and I have checked each day...NO WATER!!! I hope this helps....GOOD LUCK!!!
