Is it possible to move the air bag system on a '99 up just and inch or so? That's all I would need to get to that rear screw holding the actuator. Maybe access it by removing the windshield defrost vent somehow? I've read that removing the dash is one way on the Ford-Trucks.com/forums site, but that seems like a nightmare to me. My vacuum hot water valve is open but the blend door doesn't work.
