    Angry 1999 chevy suburban 1500 leaking water front passenger floorboards

    I know there is a lot of explanations for this problem all over the web, but i have not found the same exact issue that i am having.
    after is has rained or during a rain, when i turn the truck on, the water doesnt come pouring out from under the dash until i turn my heater fan on. Yes its water, NOT antifreeze, and i havent used my A/C in over a year (mostly because a fitting on one of the pressure lines has been slowing leaking until it stopped blowing cold altogether last summer..)

    I live on the oregon coast now and its causing mold to grow in my rig!! please help, ive cleaned under the plastic grills near where the windshield wipers mount to their motor armatures outside of the truck. You know, where you have to slightly open the hood to get to a few of the screws and its a brittle 2 piece plastic thing? now what?

    Seals are fine all the way around, this thing is still pretty cherry.

    Thanks!

    Try caulking the screws that hold those plastic grills on. Have been told that's what's causing the same problem in my truck.
