2001 GS 300 - I have water under carpet on driver side. Dried it for days. Driving in dry weather, padding under carpet wet again. Been told may be condensation from air vent going under carpet to back seat. Told could be too much condensation from vent as result of undercharged or over charged A/c system. No recent a/c work performed. Thoughts please.

 

Several members have started threads on this. I have the same problem and it's leaking from the evap core casing (very expensive to fix), being it's been dry weather, that should rule out other possibilities.

 

Have Continental extended warranty, anyone know if covered to repair/replace evaporator casing? I think evap coil covered, but casing?
