I have a 2006 with an evaporator drain line that does not drain. The AC works perfect, no abnormal cycling of the Ac. The Drain line does not drain at all. I have removed the last part of the drain line that goes through the firewall and there is no obstructions. Any ideas?

 

ANYONE? I would get it it the drain line was plugged, but it's clear.

 

Does water spill into the cabin? How do you know the drain doesn't work?
