Water getting in my cab?

[jblucolar63]

1981 2wd Blazer. It is raining here now and I have found that water is getting in the front of my cab but it is from up under the dash from what I can tell but the only place it comes down is the kick panels on both sides. Any info on where this is comming from would be great.

It is not a driving thing it does it while it sits getting rained on

I just dealt with that problem. Mine was the gasket that goes around the flapper door that closes for max and opens for normal a/c. Thats only on the passenger side. It's part of the kick panel trim piece.
But since yours is on both sides, I would think windshield gasket, maybe. If not the windshield gasket, the first thing I would do is take off the cowl panel and take a look in there too.

It's pretty common for the windshield gasket to leak.

It's on my list for spring... But I'm taking the old glass out at the house so any rust can be fixed before new glass/gasket/trim goes in.

im having the same problem on my 74, but its coming in from near where the tranny tunnel meets the firewall part up there from behind the sounddeadining board
