trying to pinpoint water leak in the cab
 
Well folks I've just about got my new to me 1997 ZJ squared away after fixing my leaky freeze plugs and desludging my 4.0. Now I'm on to the musty moldy leaking cab. Every day when I open the truck it stinks horribly with a musty odor. I went to a job a few weeks ago and when I got home the steering wheel, seats and shifter were all covered in mold from the moisture. Its also being inhabited by frogs, lol, every day I keep evicting them.

I wanted to try to find out on the forum here about all the problem leak areas on my ZJ Laredo. I did a little research and it seems that the roof rack is a prime suspect for leaks but I never have a wet head liner. My front floor boards get the wettest and the rear floor boads seem to get a little moist but not much. All the seats seem pretty dry to, maybe a little moist feeling in the front. Any ideas on where my problem area might be? Thanks

Just a shot in the dark, but how's the weatherstripping around the windshield look?

AC drain tube. Do a search, lots of threads explaining fix.

JBrady5555 08-23-2013 05:07 PM

I'll check both things, thanks guys. We actually just had a good hour of hard rain.

Is this particular thing something that leaks when the A/C is running? If so we can rule this out because I haven't ran the A/C hardly at all.

no it will leak and soak the front pass floor and the rear floors via the air duct under the front seats. every time it rains the water runs down the windshield into the cowl and threw the ac box and out the drain tube. the problem is that the drain tube gets clogged and then the rain runs in the ac ducts and all over the floor.

This really sounds like my issue, now I just need to find out how to clean this thing out.

Well here is another piece to the puzzle, the carpeted floor mats are dry, but the carpeted floor underneath is wet on both passenger and drivers side.

JBrady5555 08-24-2013 03:05 PM

Ok I just went out and had a look, I'm still not sure what to look for with the whole A/C drain tube, but I looked up under the passenger side of the dash, nothing looks messed up. I did notice when I took up the floor mats that I can push down on the carpet and end up with a puddle of water on my hand on both passenger and drivers side. Its worst than I thought, I didn't know I had that much standing water in this thing. If it is the A/C then wouldn't there just be water on the passenger side?

Passenger side, try this:

Driverside, your cowlseal are probably bad and needs to be resealed.
Heres is mine after i had scraped of most of the old seal.

very easy to fix when you open the hood.
Mine leaked through the roofrack bolts to, i removed them and put RTV in the holes and then put them back in.

thanks I will check out the cowl seal

JBrady5555 08-24-2013 03:49 PM

I just checked that black box behind the passenger side carpet and with the A/C on it has water coming out of the bottom of it. So now I just need to drill the 1/4 inch hole and clean it out with a coat hanger right? Also this still doesn't solve the driver side issue but the cowl seal is definitely dry rotted.

Pierre_r 08-24-2013 04:05 PM

Reseal the cowl and it will stop raining in.

You see the part that i have drawn a circle around, the black part in that circle is a hole that goes right in the cab.

I did both sides when i was doing it because the other side was starting to crack to

rtv?

JBrady5555 08-24-2013 04:11 PM

Also I got my hole drilled through the black box. My only option is to run a coat hanger in it. where to I need to try to get the coat hanger rod to once I enter the box. Up, down, left, right, everywhere? I'm not really sure.
