Archived Can't find the leak...

[THenningsen]

After discovering a soaked passenger side of my truck, I removed the carpet. I read multiple threads on possible leak locations. I cleaned out the a/c drain tube and extended it using 2' of plastic tubing. It rained yesterday and I found my floor to be wet again. Seems to be wettest underneath the passenger side dash area. Looks like there is a round tube that goes into the firewall. I'm assuming that it's the a/c drain, but why would it be leaking. My truck hasn't been on in about a week. I sat inside while my wife sprayed the truck with the garden hose. It's not coming from the 3rd brake light, the door hinge, etc. Any ideas?

How do you know it's not coming from the 3rd brake light? When it leaks water runs around the back window down to the floor behind the interior trim so there is no sign of anything wet. The way the floor is made it's like a rain gutter to the front.

Sounds Like you have a bad window Seal. Have you had any new windows replaced lately.

My '95 leaked exactly the way Joe G. described. Take off the cover and look for tracks. Next place to look would be the cab lights. They can leak onto the headliner and run down behind the A pillar. Might pull the A pillar trim before the next rain to be sure.

I have to agree with Joe G. Additionally, it wouldn't take 1/2 as long as you've probably already spent chasing the leak to simply re-seal the third light. Definitly can't hurt anything and at least you could rule it out if the leak continues. MHO. Good luck.

Try this one. It is a technical service bulliten and the tsb# is 23-68-97 The link is http://dodgeram.info/tsb/1997/23-68-97.htm Mine leaks but I dont fully understand the pictures. If you figure it out tell me about it. mine leaks too and it aint no brake light (its a quad cab) and its not the cab lights (i dont have any)

it aint no brake light (its a quad cab)

What's that got to do with it? I have a club cab which is the same length and floor configuration. The brake light leaked on mine.
