here in PA we finally got some rain last night(good downpoor)
i noticed this morning that my 78 cab is went on the rug from the
high beam switch then down to about the seat, it doesnt cover the whole area but about half...Where should i start to look for leaks??

Were you driving it, or just sitting in the drive?

 

Mine does the same thing. When it rains I get a little water running down inside the cab on the pass and drivers' side. I'm pretty sure it's coming from the cowl. I just have no idea how to get to the weather stripping that's there I think you need to take the dash out....anyone else have any ideas?

Mine leaked past the gasket where the wiper shaft goes through the body. It was an easy fix. I hope you guys find something simple like that; leaks can be a big pain.

[updated:LAST EDITED ON 03-Mar-02 AT 08:45 PM (EST)]Thanks Eric!!! good tip!!!

 

I've had the same problem on the right side. Thought it might be the windshield seal but that would probably have to show on the dash. Might be a crack in the cowl inlet assembly but that windshield wiper seal sounds like a good bet. Can you remove the wiper, unscrew a nut and get to the seal?

Thanks,

the inside kick panel area and then spreadin out

6t6merc, I brought this back up to ask what the gasket looks like and how to access it. The windshield wiper shaft gasket that is. Ford dealer cannot find a picture. I'm trying to figure out what's involed in replacing the seal and making or buying them.

Actually I think I found what I need in the Obsolete Ford Parts catalog. It's on page 107 0f my "obsolete 1996" catalog. Called wiper pivot shaft to cowl top seal. Part #D3TZ-17A475-A @ $3.95 eash (old price). They are round and slanted on one end and go on from the outside I believe.
I'll try to get with them next week to see if they are still available.

Thanx,

i had 2 78 supercabs in the past that had the same problem. it was leaking from the upper most corner of the windshield down to the bottom were there was a rust hole and the water came in the cab under the dash. my left foot always got wet. so i pulled back the rubber seal on the windshield and shot a bunch of black silicone in. stopped the water problem but not the rust.

on my 77 there are two rubber plugs about 2 inches in diameter way up under the dash that keep rain out of cab.they are right below the post next to windshield. they get brittle with age and start to leak
