My '94 has a leak on the driver's carpet. I have cleaned the duckbill and poked every drain tube I could find. I couldn't get any water to flow thu the drain tubes inside the door jambs at the hinges. The short tube on the side of the xmission hump stay dry on the outside.
. Some days, when it rains, the car stays dry. Other days, the carpets get wet.
The water collects in the insulation alongside the xmission hump and under the brake pedal.
Is it possible that shutting the car down with the fan switch, and hence the floor vents, open would allow the rain to get in? And if I shut the heater system down the rain will be blocked? I know this is a reach, but I'm tring to find a pattern of when it leaks and when it doesn't.
Thanks for any help.
