A/c drain hose

the a/c box is located outside of cab.

 

On my Sterling the box that houses the evaparator does not have a hose. Just has a slight increase with a small rectangular hole at the bottom center. I thought it was odd at first.

 

Hey I'm having the same issue with my 2012 Cascadia. Where exactly was the drain hose located?

 

Hey, I have the same issue with my 2012 Cascadia. How did you fix the problem?

 

The drain is probably (I’m familiar with the Coronado) located just inside of your right side cab mount.

More than likely your evaporator is plugged if the drain has plugged. Once you get the drain flowing, pull your lower right kick panel, remove the fan (you’ll just see the inside air filter you didn’t know about) reach in a wash it out.

I’ve got a garden hose fitting with a 1/4 turn valve bushed down to @ 3ft of 1/4” air line I built to reach in there. Use your phone to reach in and take a picture now and then so you can see what spots still need rinsed. You’ll probably notice a big difference in the air flow out of the vents.
