I have a "stock" 98 ss convertable with ac and the water vent tube must be blocked and I cannot find it. After use on a "wet" day it leakes out into the passenger floorboard. I tried seeing it from above and feeling it from below but cannot find it. Can I just blow it out with compressed are if I find it. Any clues would be appricated.

Either in the firewall or just under the firewall should be a small rubber or plastic tube for the drain. Just gotta keep looking. Onthe off chance, some builders let it drain behind the fender.
