Air conditioner drain lines plugged?

[GUS2000]

Well we started having water dripping in the bedroom today from AC drainage... i pulled the vent cover off and the ring with the foam on it was soaked... no water in the vent but definitly alot of water between the ceiling and the duct... have a mobile tech coming out to see what the source is... Mothership said they fixed this issue last year.. but apparanly they didnt...

What I have found is depending on any slight lean the coach has the water will flow to that side. I’m sure you have experienced when getting ready to travel and jacks retracted water will sometimes poor out one side
As for compressed air to clear the lines, I agree with RB on 30 psi or water from the top with drain grids removed.

Here was what i found in our coach when i took the AC off of the roof.. one area that was not taped correctly at the factory that was allowing cool air to enter into the attic space and then drain in the bedroom ceiling.. after this was corrected we have seen no more issue with water collecting in the ceiling..

Here is the inside of the ceiling while before the area was sealed

Here is the inside of the ceiling 24 hours after being sealed... almost all the water has evaporated and no new water pooling seen..
