Here's what happens:
When my car sits out in a normal rain or when I wash it, it drains OK. But if we get a heavy downpour, I can end up with water in the rear footwells.
What I'm looking to do is to clean out any and all drain holes to make sure I don't have a collection of leaves, pine needles, dead insects, etc., that are impeding the drainage process.
If I understand correctly, there's a channel or gutter at the base of our tops, and that can be vacuumed out to help keep it clear of outdoor debris.
But where does the water route to once it's in that channel?
In the First Gen cars, the water would drain along with the windows into the quarter panels and then into the rocker area, which had drain holes stamped into it. I'm assuming that the 4th Gen had something similar, but I can't find any doco on what the system is. I just want to make sure my vert doesn't develop rust from the inside of the car.
