Kodiak 5500 cab A/C drain location July 29, 2020, 02:05:56 pm We've been getting some water condensation dripping inside on the passenger floor with the cab A/C running. I looked outside for the A/C drain line but could not find one. Anybody have a location for the A/c drain under the hood for the 2008 Chevy Kodiak 5500? It's my 2009 Jayco Seneca RV. The pic is from the front of the A/C under the hood. You can see water dripping from the screws on the box.
