I can hear water sloshing around behind the dashboard. Does anyone know where the air conditioner evaporator drain is on the 2008 HHR and how to clear it?

The drain should come out behind the front right tire. You should see a small rubber tube exiting from the lower part of the firewall. I have found that if you blast compressed air up the tube, that it will most of the time break up the clog and it will wash on down. If that doesn't work, you can back flush it with water carefully.
