bubbles in ceiling

[Sdexte]

I have a 2019 HC 373RD and have recently noticed bubbles forming on the bedroom ceiling material just ahead of the slide. We poked the bubbles with a needle and yellowish watery liquid dripped out, not alot but noticeable. I checked the roof for any place where water could get in but it was all good. I did not see where any water would have gotten into any of the sealed areas either. Does anyone have any ideas or had similar issues? One thought occurred to my wife was that she noticed them after we started using the bedroom AC, could there be an issue with condensation from it? It isn't a major issue YET, but trying to figure it out. Thanks

Having the drain holes blocked on the AC is a common issue and another know issue is having the extra AC mounting holes not filled with something that stayed in the holes. Others have found that the AC wasn't seated properly or the hole taped properly.

Where would I look to find the drain holes? Do I take the AC cover off? We’ve run the AC quite a bit since we got it but we just started using it when we got into Arizona this week.

I had the same issue on my 2019 374 last summer. It was my front ac leaking thru ceiling. The drain was plugged I need to repaint the ceiling along the seam they just left it for me all yellow. To much work for them I guess lol

Pull the roof cover off, usually four screws, you will see the drain holes are in the pan.

When my drain holes were plugged, I took AC cover off and took a hacksaw blade and slid it between the rubber roof and pan to clear away crud ( take care not to damage the rubber roof) then I used a small straight screwdriver to clear the drain holes and once more cleared any crud between roof and pan. Now a yearly chore.

Check the crank up antenna, as most are mounted by the bedroom slide and can leak.

I have something similar. My unit has two A/C and both ceiling panels that the A/C is over has black streaks that will not come off. I've tries simple green and cloth dampened with bleach. I've used a bore scope and looked at top of panel and it is dry but has the bubbles on top but not bottom of panel.

A bubble formed in our ceiling, took Monty to CW. CW brought it to our attention that we lost the top to the mushroom cap. We were dummies, didn't know the top was gone--now I know to look.
