I run my ac on the recycle mode and don't have the problem. From what I understand, it can only be properly cleaned with the chemical spray. I turn off my ac and let the fan run with the windows down for about a block before shutting down. Then when I run the ac I use the fresh ac mode for a block with windows down before using recycle. If you're still under warranty have madera toyota check if there's a problem. You also might want to try spaying lysol into the exterior intake vents. Try it using fresh ac mode then switch to recycle. This is only a temp fix, you will have to do this about once a week. I also used some ac spray cleaner at kragen that is used on interior and exterior vent. I used to have the mold problem in my old jeep grand junker. It is a nasty and annoying problem, it does't seem like this should occur in a truck that's only 2 yrs. old
