Having problems with your Cars & Trucks ?
Poor air flow through defroster vents
\015 I have good air flow to floor vents and good air flow to dash vents. When I switch to defrost I have good air flow to side window vents,but poor flow through defrost vents. The door actuator has full movement to both stops. I do hear a whistle noise when on full defrost mode. Do the side window vents and the defrost vents have a door between them?\015
