Leaking Town car

Jinx · Jan 5, 2019

At first I thought someone had spilled a soda and did not bother to tell me. So I just shop vacc’d it and let it dry out. Well after 4 days of rain I noticed condensation build up inside so I opened the doors to see and there was about 1/2” of standing water. It’s only on the passenger side. It’s more pronounced in the back. The windows were up and the door seals look like they are in good shape. What I want to know is how is the floor getting soaked but there is no sign of water damage or dampness any where else ?

So after 20 min of running the car on high recirculating heat, followed by to hours or radiated heat (safely) I pulled another 2 cups of water from the rear passenger floorboard.

All of those images are so closed in that it's hard to tell from shinola.

Is it a sunroof car?
front seat, back seat, both?
Was it sitting? Being driven?

also: pics of the cowl, rear window, jambs in the trunk

What drain tubes to Town Cars have? You already check evap drain?

No sun roof
Both front passenger and rear passenger floor boards are wet. More in the rear.
Definitely sitting for several weeks
Not familiar with this car as it is not mine do no idea about drams or tubes.
I can see about getting requested pics later.

What’s really weird is that there is zero dampness above 2” from the floor boards.

Back when I still did automotive ac-used to always be the hvac box,either the drain for the box would be clogged,or the drains in the cowling would be clogged and eventually make its way to the hvac box,and then overflow into the floor. A car that sits usually has a cowl panel full of leaves and other junk

Will look at that tomorrow.

Pull the kick panel on the passenger front, could be a cowl or windshield leak and running down the inside and out a seam at the floor

Pics as requested
One or two leaves in the cowel and completely dry.

Floor boards damp again but not nearly as bad. Must be something holding the liquids like a sponge.

Pulled the front kick plate and pulled back carpet. Pool of water sitting under mat. Trying to load video after picture.

No luck with video now

Cowel removed and carpet pulled back. That rubber barrier is soaked. Also starting to get drainage through weep hole in floor.

You need to look behind all of the door panels and see if the drain holes are plugged.

If it's been sitting for a while, the door bottoms can fill and overflow into the car.

I don’t think it’s the doors because it’s completely dry at the door sills. Even under the runner from the kick plate.

Rear seat removed. Rear passenger trim pulled and carpet lifted... so much water !!! Think it may be left over from when it rained with the windows on that side down? Granted that was 7 weeks ago that it happened but I never considered the extent of water trapped in the foam?

Holy chit!!

That water will stay under the carpet for a loooooooooooooooooong time.

I fought similar to issues to what you're having on my daughter's Cadillac CTS. Their ended up being one large contributor and several small ones that I found. One of the small ones was fixed when the windshield was replaced.

That car had 'junk' in nearly every water drain. The previous owner had obviously kept it parked beneath one of those trees that poops the little helicopter thingies along with some tiny popcorn looking stuff.
