Passenger floor flooded out
Posted by: upnorth1 ()
Date: August 06, 2011 05:54PM

Went to a car show in Ashland Wi today. Called early for rain and hail threat. We drove thru 50 miles of moderate rain, when we got home my wife's stuff that was by her feet was soaking wet. Carpet is drenched.

I figgure it has to be from a plugged drain from the front valance area, but how do I find it?

Thanks!

Every time I have approached that issue, I removed the windshield
and found the drains plugged up and usually some additional rust, or rot.

You may also want to removed the dash pad, I have found several cars rusted badly under the pad, and the water seeps from the underside of the windshield

Your mileage may vary!!!!

Were you driving a LM? Sometimes the rockers get plugged up with "yak" and the water can't drain, overflowing behind the plastic of the kick panel and soaking the carpet that way. I had that in my 68 and didn't even know it, but was going crazy trying to find the water leak. Sold it before I learned about that particular thing.

So slide under the car{not an easy feet for my size} and look for the rocker drains. open up as possible and hopefully she drains?

Much bettern FIRST alternative to pulling windshield...

Along with the windshield drain issue, I've seen Corvairs where the sheet metal under the front cowl is like cheese cloth from rust. Remove cowl valance panel, put a drop light under the wiper mechanism and look up under the dash.

Windshield leaks and rust holes have been well covered above and are pretty obvious when you're getting wet socksgrinning smiley.

Rocker drains plug up in several places. The most common is behind the kick panel vents inside the car. You have to remove the plastic grille and the larger plastic kick panel. Once it's out, you reach in and yard-out the leaves and pine needles that plug the quarter-sized hole at the bottom. If this area isn't clear, your lower fender and hinge pillar will be bathed in water and rust out. Once you have it clean and dry, this is a good chance to paint in there. I'd suggest POR-15 or similar rust converter product.

Once cleaned and painted, you can reinstall the kick panels but you'll probably want to freshen or replace the dum-dum body sealer that's between the kick panel and body.

The rocker panels have drain holes at each end but it's pretty obvious when they're plugged because the rockers will fill up with a gallon or two of water and this will slosh noisily until the water drips out.

A cracked air conditioner box will cause that problem, don't ask how I know.

If all drain holes are clear and even if not........I agree on the kick-panel vent housings. They can be a bugger to reseal to the inner fender. I always put 4 "extra" screws on mine, making a total of 8. The 4 origional mounting screws behind the vent grills never seem to hold the panel in place secure enough to make the duct seal goop keep the water out.
