1984 LTD Country Squire wet floor passenger side

[Master Shake]

It feel likes water, doesn't smell or feel like coolant so I dont think it's the heater core. Also the wetness is concentrated on the floor pan it doesn't go up towards the firewall, the door or the center hump. All the insulation is wet, the factory hard insulation is peeling from the floor. But again doesnt go up past the floor level. Any ideas?

Did you check the bottom of the floor pans for holes?

Yea if it doesnt go near the door the only good explanation would be rust holes in the floor probably. If it was near the door could be clogged door drains that just spill in (happened to me), or bad weatherstripping.

Both may wagons are wet on the passenger side. The 88 is such a leaker that it would make a pond over there if it rained a lot. Drill bit fixed that.

Seriously, I have looked for the cause and I can't find it. It comes in behind the firewall insulation on the 88. I assume someone missed some seam sealer somewhere. And on my car, the I didn't suspect the firewall since it wasn't wet but if someone sprays water on the outside of the car, I can watch the stream inside. The water runs down and get the carpet wet but the firewall just is barely wet, or not at all if it has been a few hours since the water ran down.

Okay, found it.

I had a buddy hose the car down from above while I was looking through the passenger foot well with a light. Right away I found a stream of water coming down from the firewall by the center hump.

I got out and looked under the hood and found a wire going into the firewall with no grommet. The water follows the wire and flows freely into the cabin. I didn't have a grommet on hand but I put some of this butyl tape around the wire and plugged it into the hole. Seems to hold so far. Shame though, had to rip out all the sound deadening and insulation because it was all soggy and gross.

Glad you found it! I'm gonna check mine now lol, those floor's look like they've seen many wet days through that hole.

I like using ultra black to fill in holes like that.

I've been chasing a water leak in the same spot on my 92 for years. Caulked everything I could find, still leaks. I'm done. When it rots out it won't hold water any more. Problem solved.

I know how you feel.......have the same feeling concerning my '86 Tudor MGM

Till I can pull the rear drivers side inside plastic moldings off of the rear seat window area, this is what I have done.......to at least keep a good deal of water from soaking into the carpet like a river.......when it was dry, I laid out two large rubber mats in the drivers side foot well.......on top of that I placed a giant XL sized "Absorber"....you know those synthetic chammy's? Now when the water comes in from the area of the seat belt opening in the molding the water hits that chammy and is absorbed to a geat deal....the extra mats keep the water from penetrating to the carpet....crude but effective till I can get to that leak!
