Ok, thanks for all the help and hints as I worked out my engine issue. Now that I think it is good, time to work towards getting the heater vents to work properly.
I assume there are shutter doors that open and close to redistribute the air. I hear the blower motor going well but not much air coming through. When I move the selector to defrost windshierld, I hear it change but it doesn't change enough to blow much air to the windshild. In fact, no matter what I select, not much air comes out of any vent.
Are these electric or cable actuated doors. Any ideas?
