AC Drains
The drain tubes connect to the pan under the AC unit.
You can check if they are connected properly and moving water by popping off the ducted air intake vents (4 of them) on the ceiling inside the coach.
Look for a T-junction with 1/2” clear plastic tubing. Check to see if they are connected properly - you should see water / moisture inside when the unit is operational.
I’d start there to determine if the tubes are clogged....
If one of them is clear but dry when the AC unit is in operation then you may have an issue in that the AC unit itself could be toast, and simply not exchanging heat, which causes the condensation in the first place.
Check to see if both units blow cold air. If its cool outside put them in heat mode and make sure they blow warm air. Test them one at a time for about 10 minutes continual running.
If it seems that one of your units is simply circulating ambient air then the compressor could be toast or you may have a freon leak. Both of these issues require AC replacement. Ask me how I know.
