I just got a 1997 Dodge Ram 1500 4x4 reg cab that the floor gets wet when it rains. It isn't the windshield, third brake light or the clearance lights, so I'm suspecting the possibility of the cowl drain. I just need to locate. Any help? Also, is there one or two? Thanks.

Update Finally got frustrated with all this rain and sent it to a shop. They found it. Someone had installed aftermarket speakers in the doors and the routing of the wires pushed the vapor seal open at the bottom.

 

What part of the floor is getting wet?

 

It kinda pools on the mostly the passenger side of the floorboard and somewhat on the driver's side. I've pulled the door molding and kick panel, but couldn't really tell where it's coming from since the firewall insulation is also wet at least half way up towards the dash. Don't really know if it is wicking up from the floor or running down from the cowl. That's why I'm asking about the cowl drain.

 

I'm not sure where it is...... May have to strip most of the interior, and then have someone hose it down, while you sit inside, and see where it is coming from.

 

I was afraid of that. Right now it looks like rain for about a week and my garage is almost full of stuff. What I might do is to remove the windshield wipers and the cowl cover and take a good look behind the hood hinges. I do know the truck has quite a few fir needles in the cowl area. Thanks.

 

How do you know the clearance lights/third brake lite seals are good? Gaskets dry out and the plastic warps over time and causes them to leak. I would double check them.

 

I did remove them in order to check and reseal. no moisture at all either under the gasket, on the screws or anywhere in the lenses.

 

Could it be raccoon urine?

 

It didn't taste like it.
