Wet Passenger Floor

[smiller5676]

I have a 2006 Holiday Rambler Admiral SE 30PDD. When I run the AC from the motor, not the roof mounted AC the passenger side floor becomes wet. I have located the drain hose and it's dry as a bone. I'm certain there is condensation building up inside and spilling out creating the wet floor. I don't know how to access the unit to check inside. Any help or suggestions?

You might try probing the drain hose with a coat hanger or piece of wire to open it up, or give it a shot of compressed air.

Be prepared for a whoosh of some nasty water when you get it open. Don't blow on the tube with your mouth. Legionnaire's disease is known to lurk in places like that. Wash your hands afterwards.

Ditto on compressed air, blow both directions, should be an easy fix.

I would start with low air pressure (like 30 PSI), then increase if needed. A 14 year old drain hose could rupture if plugged hard enough and too much pressure is applied.
