Abstract

A closure assembly includes a housing, a sensor, a door, and a primary actuator. The sensor is disposed within the housing. The door is supported by the housing and is movable between a closed position and an open position. The sensor is exposed when the door is in the open position. The primary actuator is operable to (i) apply a first force on the door to move the door from the closed position to the open position and (ii) apply a second force on the door to move the door from the closed position to the open position when the first force does not move the door into the open position.
