Condensation at bathroom AC ceiling vent
This is my first rig that has an AC vent in the bathroom. Daytime temps have been in the 80s and high humidity. I always keep the bathroom outside roof vent open and run the exhaust fan when showering, but noticed that condensation is almost always present on the ceiling ac vent. There is no condensation at anybody the other hand ac vents in the rig. Is this normal?
Ac functions well and there is no possibility of condensation traveling inside the ceiling duct as the bathroom ac vent is higher than the actual unit itself.

Pull the bathroom AC vent and check to make sure the duct is properly taped and you aren't leaking air into the ceiling area. Condensate around grills usually indicates that you have an air leak and you are blowing cold air against something warm and it's possible you are blowing cold aor on the cieling material and it's dripping down.

I recently redid all foil tape in the openings. I don't think that is the issue. I wonder if leaving the bathroom roof vent open is causing excess humidity to build up?

My garage vents get humidity around them when I close them and use the garage as a screen porch.
They are simply reacting to the ambient humidity vs the cold being contained by the closed vent.

That is what I was thinking. Leaving my roof vent open in the bathroom on top of humidity from shower must be causing this. Not a big deal.
Thanks
