Now that the warm weather has returned I have noticed the same odor problem with my 04 DC AC system. If I run the AC untill I shut the car off I see a large amount of condensation dripping under the truck. I am assuming that most but not all of the condesation is being routed away from the heat exchanger and the water that can't get away begins to promote mold growth and smell the next time I turn the AC on. If I turn the AC off 5 minutes before I shut down the truck and run the fan only I don't have the problem next time I run the AC but I don't feel like I should have to do this.
Has anyone come up with a mechanical fix for this? I am not really interested in spraying some type of chemical cleaner in there because I'm sure the problem will return. Has anyone taken apart the condensation catch tray? How do you get to it on the DC? Is there a design flaw that causes it to hold water?
