HerbieHymer is a 2008 A class and the heating works fine except that two vents under the dinette don't expel hot air. The cabinet all around them is warm so something's stopping them expelling air and I can't for the life of me work out what it is.
The other habitation vents work fine. Does anyone have any idea?
