Water leaks from the front visor on my convertable. Someone said there are drains on both sides of the top frame of the windshield. If plugged, may be where the water is coming from. Where are the drains located at top fo the windshield.
If there are any drain holes, they should be at the pillars which would have a tube leading down to the kick panels but I doubt there would be any as drain holes are for vehicles equipped with sunroofs. The convertible top could have a crack or damage causing the leakage.
