Where is the AC drain tube you speak of? Is it underneath the truck? In the meantime, I'll look in the manual.1. Make sure that the AC drain tube is clear and draining outside the truck properly. The problem still exists in newer Ttitans. Even if you don't have any water on your floorboard you still want to do this mod. Check it out...
The vent you are talking about is the fresh air vent or cowl vent?4. Follow up with Frigi Fresh every 3-4 months by spraying it into the vent and running the heater for 20-30 minutes. Use the fresh air function as much as possible instead of recirculate.
You can the drain tube via the engine compartment. There's a photo in the link I provided.Where is the AC drain tube you speak of? Is it underneath the truck? In the meantime, I'll look in the manual.

Thanks for the suggestions! I will try as you say. I often use recirculate. I've been doing so since I've bought it. And the humidity in Houston does not help either. It was ok in the winter, but now that the heat is back, it funks for the first few minutes you turn it on.
