The defroster/defogger does not clear frost/fog from passenger side windshield & window resulting in dangerous driving condition with even only driver in vehicle. Problem is extremely dangerous with 7-8 passengers in vehicle. Dealer has seen "several" others; condition "normal." Two trips to dealer and problem still exists. Same problem reported ODI id 852577 1998 Chevrolet Venture on 02/12/2000. Problem is due to: 1. poor engineering design results in too small defroster opening for size of windshield 2. as a result, airflow is directed towards driverside to clear driver's side, leaving passenger side with little or no airflow. Resulting in very dangerous condition!!! help!!!!!
