make sure the devider is sealed and tight(the foam board between intake and exhaust)

Don't know a thing about AC, but we are taking off on Friday, I'll go up top tomorrow, pop the cowling and see if something obvious calls to me. I'll look for that divider as well. Is the problem most likely up on the roof, or under the cowling inside the camper? I'm guessing up top is the place to start?

Only so much I know what to look for before I'll have to take it in and pay somebody.
