AC condensate not dripping

[MilehighRam]

Ive noticed a funky smell in my truck when the auto start/stop kicks back on and the ac is running. I read on this forum to make sure the ac condensate drain is dripping; mine is not. Ive put a rifle barrel cleaner up in there and nothing. I can feel cool air pumping out of the drain, but no water. Im in Denver, so we have low humidity, but there should still be something dripping. Any suggestions?

I've heard compressed air is better. Running a barrel cleaner like that up there might just push it all together into a clump. Others might have more experience though.

Im surprised at the ac issues that exist on these trucks.

If you’re feeling air, there shouldn’t be a blockage. Plus the truck is new so I doubt anything has built up yet. How humid was it outside? What was the dew point? How long was the AC running? All relevant factors to how much condensation would be occur and cause the evaporator coils to drip water.

The musty smell is likely bacteria growing on the evaporator coils because when you shut the truck off, air stops blowing on the coils and it stays wet, gets warm, and is in a dark space... all causing bacteria growth. Common problem on all vehicles but some are worse than others. If growth is the issue, spraying cleaner on the coils is the only way to completely fix it. Running the fan without AC for a few minutes at the end of every drive is the only way to completely prevent it.

This . . . I turn my a/c off about a mile before I get home...
