When I encountered the problem on my Tundra I couldn't find the drain tube. I checked with the local Toyota dealer and they said it is concealed and takes maybe one and a half hours to get to it. That seemed excessive time wise so I said I would bring it back in and have them take care of in on my next service.

Another symptom of that being the problem is that when the A/C in running on most vehicles there is condensation water dripping from the car. On our Acura it is constant and significant. On the Tundra I never see it. (that is why I went looking and told the dealer)

Sound familiar to any of you?
