1998 Chevy Truck A/C Drain

You'll have to crawl under your truck about where your heater is on the passenger side. You'll see a hose there that looks like it may be crimped. Get a piece of coat hanger and shove it up there a little way and twirl it around and up and down. Have something so you don't get your eyes fille d with water as that's what's going to come out. That should take care of it unless you live on a dirt road as with the water and dust it may do it again.
