2nd Gen Non-Engine/Transmission Water in my floorboard

Doors

Our extended cab got new door seals about 1 1/2 years ago and we still got a leak and soggy carpet this past winter. I recently moved the striker pins in to pull the door closed tighter. I am also not allowing the truck to be parked in a twisted condition. My yard has a downhill and twisting spot that can cause a high rear wheel and low opposite front wheel, me thinks it twisted the cab a bit and might make gaps at the doors.



I replaced the mat under the carpet, found the same chopped blue stuff at an automotive upholstery shop. Repainted the floor pan and reinstalled.



Labor was nasty, but cab has been dry for 3 months and lots of rain.



Above info from previous posts is darn good also.

My 96 had the same problem and I added an extension hose to my AC drain line and the leak stopped. Simple fix for a manufactures screw up. Where the line exits the firewall was only 3/4" long. When moving down the road the air flow was driving the water back and the buildup would spill over and run down behind the foam backed rubber down into the carpet. When I first noticed the leak I resealed the 3rd brake light, checked the door seals, checked the backseat windows, accussed my dog of peeing inside my truck, everything. Then the idea on the hose extension from another TDR member saved the day! Hope this helps! Good Luck!

I posted the below post on 9-27-2007, I hope this helps. It stopped the water on the floor for me.

There are two main causes of water on the floor board. The most common cause is the Center High Mounted Stop Light on the back of the cab. The seal sometimes does not seal properly. The second most common cause is the drain off of the A/C system is clogged.
On my truck, I sealed the CHMSL with a little silicone while installing my satellite antenna. This did not solve my problem and the floor was wet from about just below the carpet line in the front to almost the back seat. I took out the back seat and loosened a lot of the screws for the trim and propped the carpet up for drying. I even was able to remove about 6-8 cups of water. I then went to NAPA and got the hose attachment that fits around the outside. Here's the link I used.

water leak from under dash...

In short the part # at NAPA is 9808. It is a small heater hose that has a 90 bend in it. I used a stainless worm-gear clamp and attached it to the bung on the engine side of the fire wall.
No problems since, no mater how much water came in. If you would like pics let me know and I will take a few and post. It took me more time to go get the part from NAPA than it did to install. I also cleaned out the drain before I installed the hose. I hope this helps.
