    I have had this problem for YEARS! Water seeping into the cab. So I always try and park facing downhill!! Usually works. And finally after all these years, I am getting around to doing something about it. The water comes in from the upper left corner of the dash, body seams leaking it appears. I have sealed and resealed the windshield many a time! I have also removed the dash, cluster, turned on the garden hose and soaked the hell out of the area to try a pinpoint the exact leak to no avail. I order from LMCtruck.com, a pair of fender seals and hood hinge deflector seals and it's a big job to install them. Involves removing the fenders, hood, cowl, inner wheel wells, etc... Anyone else have a similar problem? How did you solve it? When I remove the fenders, any areas I should be checking and welding or will these fender seals do the job? Thanks!

    If it's definitely coming from around the windshield you may need to remove the windshield and check for rust holes in that area. If everything seems ok then get a new windshield gasket and install it, using adheasive between the gasket and windshield frame.
    It could also be the door seal. The water runs down along the gasket and down the A-pilar and leaves a nice wet spot on the carpet (ask me how I know /forums/images/graemlins/tongue.gif).

    It's not the windshield gasket leaking; replaced it twice and sealed the hell out of it! It fact to determin if the windshield is leaking or not, we "duct taped" the windshied and ran water over it. Still leaked but not from the windshield. No other openings. The vents have new gaskets and trial and error using the garden hose shows the vents to be water tight. No, the leak is coming from the body seams. I took the flash light and got up under the dash and pointed the light up toward the dash/windshield and I can see the water seeping in along the seams. What are the fender gaskets for anyway?! I'm figuring why have rubber gaskets that are about a foot long by 3-4 inches wide ubless they are needed to seal the water out? Oh well! I have a project to do installing the fender gaskets! Once I remove the fenders, maybe I'll spot a hole or two.

    What we do on boats with leaking windows is to use a water soluble marker (not a permanent one) and draw around the area you think it is leaking. Then wait for a good rain or use your garden hose. The water will remove the marker ink where the water runs down. This makes it easy to see where the leak is.

    I would really check the window area for rust, as well as the seams near the roof of the cab. Water runs downhill. It could be running inside the roof pillar.
