The air doesn't always blow out of the selected vent very well. Now i'm starting to notice that when I'm going down the highway it doesn't want to blow out anyhwere. The fan is blowing strong and all speeds operate. It seems like the little vacuum motor that runs the selector door may be worn out? I can hear some hissing comeing from the blower box area.
If you think this is the issue how do I access the vacuum motor?
