The air conditioning vents emit a clicking noise. When I set the vent
selector switch all the way to dash vents they emit a click once every few
seconds. I moved the slector one click stop towards split vents and it stops
Any ideas? The AC seem to work jsut fine, and it seems to direct air where
ever it is supposed.
