found this last weekend and thought I would pass this along also. Been having issues with the pass side carpet getting wet and staying wet. I 1st thought it was the coolant, but it didn't have any smell. I also thought about the drain for the evaporator, but still couldn't find the problem. So I decided to lift the carpet up, dry the flooring, and crank the truck and let the AC run for a while. After sitting under the truck(while running-sucks) I was able to see the water drain out of the tube @ the firewall. What was happening, was as it ran out it would run under and back down the tube towards the firewall. There is a seal, but it was still getting around or through it and wetting the floor. Not sure if this part came with a drop hose from the factory, but mine was just the tube sticking through the wall about an 1". I found a 90° spark plug boot worked perfect. That had about a 1/2" ID that fit right over the tube, turning the boot straight down would force the water straight down and not back onto itself. Sorry to be long-winded, just want to help out. I also used a small hose clamp to lock it in place. Later,Chuck

just realized I posted this in the drive train area...should be in non-drive train...sorry about that.

Thanks. I was wondering where the water was coming from. I thought my wife wasn't shuttng the door all the way.
I'll get under there tomorrow and see that is it.

Yeah,
This has been talked about alot here. From the factory it had a 90* hose on it. They fall off over time.
Glad you found it.

mine gets soaked on the drivers side, but Its coming from the back of the cab... I stuffed a paper towel down there and it stopped it from coming forward when it rains, but I don't know where its coming from back there...

I too have a heater hose running from my AC drain, back to the frame, works great, 2 years now no problems. I had the wet passenger floor too.

Also I siliconed my 3rd brake light, it leaked something awful. I have a topper so I don't need it.

Do as Infidel suggests, turn the AC blower to high, use a squirt bottle full of dish soapy bubbles, spray 3rd tail light, blowing bubbles will show your leak.

When I did that I found two leaks, one on the 3rd taillight, the other in the upper corner of the rear sliding window. Resealed window, fixed that one too.

that sounds like a good idea, I haven't seen any other water problems, but it never hurts to check. I mean, how often do you check for a wet floor board near the rear.Chuck
