AC roof seal

[79fasteddie]

Found water dripping from interior ac grille after rain storm twice recently. Also from skylights, once from the rear and once from the front, so I am presuming the ac is the problem. Is there a seal that needs to be repaired on the ac? Didn't see a seal where the ac sits on roof but a seal between the upper and lower ac unit. This is on a 2009 27fb classic.

There is a seal between the upped and lower units. I would replace that, plus reseal any seams and/or areas around the vents, skylights, plumbing vents, etc. An entire separate discussion can be had to cover the different ways of accomplishing that. From my experience, I resealed the seams on the roof of our Avion by first cleaning out the old stuff as best as I could, clean the surface well, then used ParrBond in the seams, covered by Eternabond Alumibond elastomeric sealant tape. I doubt I'll ever have to mess with those seams again (but I DO keep an eye on them).
