Look for a clogged A/C drain tube on the firewall on the passenger side. It's a short 90 degree rubber pipe held on by a clamp. It's probably just full of gunk. Snip off the end or remove it and clear it out. Plymouth hasn't fixed this recurring problem on it's smaller cars for over 40 years. Probably creates hefty repair bills for it's dealers. A definite D.I.Y. Took me literally 10 minutes to fix mine after getting "water in the shoe" for several weeks.
heater core is shot...
The ac drain is plugged. The drain hose is on the firewall on the lower passenger side. ...that, or your heater core is leaking.
If it's leaking clear water, probably a bad door seal or a plugged cowl drain or a plugged AC evaporator condensation drain. orIf it's leaking engine coolant, probably a bad heater core.
IT can cut of the water drainage flooding your area underneath your pipes+If you have wooden floorboards it can rot your floor away
Passenger's side? Could be a leaking heater core
have your heater core checked its probually leaking
There is a drain on the outside firewall that is clogged.
more than likely the heater core is leaking
AC condensation drain.
you could have a heater core leaking or your windshield is leaking and the water is running down behind the dash and onto the floor.
Does your jetta have a rear spoiler? I was told that mine was leaking like that and that the spoiler was leaking. I haven't fixed it yet though.
If that water is engine coolant, the heater core is leaking.
