We recently purchased a 2007 Alphard, and after using it for a while with the AC running I have started to hear a dripping sound coming from the AC unit. Looking underneath there is no water dripping from the AC drain hose, I have check this thoroughly and the hose is completely dry.
So I think there is a blockage inside the AC unit, Google says that a good blast with compressed air can clear the blockage and get the water flowing out of the unit again.
Has anyone had any experience of this on an Alphard? Just want to check it's not going to damage anything, and whether the problem could be something else.
Many thanks.
