Jeep Wrangler Problem
Average Mileage: 77,500 mi (60,000 mi - 90,000 mi)
Water leaked into the passenger side but only happened when the car was in motion... after see how the drain tube was installed I noticed that while driving water would be forced against the firewall and back into the veh. I fixed this issue by installing and extender to the drain tube that faced down (at an angle)now the water didnt have a chance to back track. problem solved ..havent had a drop on the passenger side..and the Jeep now has 130k miles

A/C condensation drain sticks out about 2 inches through the firewall. It is practically horizontal. At highway speeds it is assumed airflow will not allow drainage. A hose extension with downward bend is avialable from dealer. However a short hose lenght from Home Dopot is just as effective.
