When I bought my '83 pickup in April it had significant leaks in the cab...I didn't know exactly where but the carpet was always wet after a typical springtime FL monsoon. First I found one of the rubber plugs missing from the hole behind the seat, so I replaced that. Then I found that the hole in the passenger side where the antenna goes was letting some water in, so I put a grommet in it and some sealer. The cab still leaked and fortunately for me the windshield had a crack that grew and grew until the insurance replaced it and the rubber seal. My old seal was toast and after the replacement, I hadn't leaked a drop until today. We have an approaching hurricane which is dropping lots of water, so I thought I'd check the cab for any leaks. Sure enough there is some water on the driver's side floor, right where the cab mount bolt is. If I follow the drops of water, I can see that there is some water coming in right in the lower corner of the windshield, almost like it pools in that bottom corner on the outside of the windshield and slowly leaks its way in. Anyone else have this problem? The windshield guy told me NOT to use silicone on my windshield for some reason (his english was so-so). Should I cut a slit to act as a channel in the rubber seal in that corner to allow the pooled water to escape?
