wet floorboards

[John P.]

I generally avoid driving my C2 convertible in the rain. However a recent need for garage space necessitated some exposure to rainfall, uncovered.

I ultimately found wet carpet on passenger and driver sides. There are no debris in the cowl wells. Lots of heavy rain though.

I have owned the vehicle for 20+ years, never had an issue, no recent windshield work. What is the most likely source of leaking in this scenario?

Front weatherstrip on the convertible top? Also do the side windows fit perfectly on the weatherstrip? If strong winds it might force rain in either area. I will say, however, that I would suspect the windshield even though you haven't had any work done recently.

John,
You state that there is no debris in the cowl "wells". It's still possible that the drainage area between the cowl wells and the exiting frame area could be clogged with debris. This would be the most logical explanation for the leakage you're experiencing. Have you run a coat hanger with a hooked end up through the exit hole near the frame rail? If not, that would be the first thing I would do to check for blockage. Alternately, you could try to use compressed air from the top and blow through the drain hole.

How about the drain hole below the left air vent.

Remove the left air vent cover ( I know a pain ) and use a mirror and look down. there is a drain hole at the bottom. Unplug the drain hole if clogged. You can see the drain hole from under the car.

Im not sure I know exactly where the drain holes are located.
