My 2011 Windjammer 3008W does not have air coming out of the vent in the bedroom. I removed the register and there is an air duct attached.
Do I have to remove the insulation under the trailer to find out what is going on?
We live at least six months a year in the trailer and really do not want to let it sit at a dealer while they decide what to do to fix the problem.
For now we use an portable electric heater to warm the bedroom.
Air does get to the bathroom with plenty of volume.
Mine rig is in the shop for this very problem. The vents are rectangular. All of my vents that are running from front to rear (lengthwise) have warm air coming out. All of my vents that are running left and right (lengthwise) have little or no air coming out. The bedroom's two vents run left/right. Gets chilly in there.
