Last night while I was sleeping, it rained pretty hard (I guess). When I went to sleep, the passenger window was down maybe 2". When I got up this morning, there was a HUGE puddle of water in the center of my cab (Columbia). The passenger side of the truck is completely dry, as well as the drivers side. Nothing on the dash is wet, nothing in the sleeper is wet - just the section between the seats and the lower-dash "bump out" (where the "garbage can" is). My printer is sitting on the passenger seat and I know the water didn't blow in, because there's no water marks on the printer paper.

I looked close and you can't see anywhere that water ran down on the inside of the windshield (like they normally would). I've got a gallon jug of water behind my drivers seat, but there's no leaks in it and it has the same amount of water that it did when I set it down yesterday after making my coffee.

I'm simply baffled.

 

Are you sure you didn't pee in your sleep

Garh... ye landlubber... what water?? sez aye ...that? (stomp-splash)

 

Have you looked up?

 

You might check the clearance lenses, see if there is maybe a couple with bad gaskets. The Century's used to be bad for leaking there.

 

The clearance lenses are in the visor. No water coming from anywhere in the ceiling that I can see. No sunroof, so nothing there. I've yet to figure it out.

I'm starting to wonder if I actually DID get out of the truck to pee when I woke up now. LOL.

 

Well.......I was being nice and not gonna point out the obvious.

Maybe you thought the gear shifter was the urinal in yer dream??

 

You're right. The clearance lights are mounted in the visor, and the visor is "Pop-Riveted" into the body metal. I've seen where those rivets have decided to leak. It takes a bit of digging to get a look at them and see if there's any tracks from water running down from one or two of them.

GaRrr.. wait a minute... (splash-splash) this is what?!!

(mutter-mutter sulk)

 

Found the leak (thanks to a downpour this morning). It's coming down the center of the split windshield, behind the divider. They're going to silicone it up this weekend.
