An apparatus includes a vent valve movable between a closed condition blocking air flow through a vent opening and an open condition enabling air flow through the vent opening. A door position sensor assembly is operable from a first condition to a second condition in response to movement of a vehicle door from a closed position to an open position and is operable from the second condition to the first condition in response to movement of the vehicle door from the open position to the closed position. An actuator assembly operates the vent valve from the closed condition to the open condition upon operation of the door position sensor assembly from the first condition to the second condition and releases the vent valve for movement from the open condition to the closed condition upon operation of the door position sensor assembly from the second condition to the first condition.

An apparatus as set forth in claim 1 wherein said door position sensor includes a plunger having a first position when the door is in the closed position and a second position when the door is in the open position and a spring biasing said plunger toward the second position. 3. An apparatus as set forth in claim 2 wherein said plunger engages the door when the door is in the closed position. 4. An apparatus as set forth in claim 1 wherein said actuator assembly includes a force transmitting member connected with said vent valve, said force transmitting member moving from a first position to a second position upon operation of said door position sensor assembly from the first condition to the second condition, said force transmitting member moving said vent valve from the closed condition to the open condition when said force transmitting member moves from the first position to the second position. 5. An apparatus as set forth in claim 4 wherein a first end section of said force transmitting member extends into a slot in said vent valve to provide a slide connection with said vent valve. 6. An apparatus as set forth in claim 5 wherein a first spring urges said force transmitting member to move said vent valve to the open condition. 7. An apparatus as set forth in claim 6 wherein a second spring urges said vent valve toward the closed condition. 8. An apparatus as set forth in claim 6 wherein said first spring urges a plunger of said door position sensor assembly toward a first condition. 9. An apparatus as set forth in claim 4 wherein a solenoid moves said force transmitting member from the first position to the second position to move said vent valve from the closed condition to the open condition upon operation of said door position sensor assembly from the first condition to the second condition. 10. An apparatus as set forth in claim 9 wherein said door position sensor assembly includes a switch that closes upon movement of said door position sensor assembly from the first condition to the second condition. 11. An apparatus as set forth in claim 4 wherein said force transmitting member includes first and second portions pivotally connected to each other. 12. An apparatus as set forth in claim 1 further including a damper which delays movement of said vent valve from the open condition to the closed condition for a period of time sufficient to enable air to be conducted from the passenger compartment of the vehicle after the vehicle door has closed. 13. An apparatus as set forth in claim 12, wherein said damper includes first and second portions movable relative to each other, said first portion being connected with a base and said second portion being connected with said vent valve, said second portion moving with said vent valve relative to said first portion and said base during movement of said vent valve relative to said base. 14. An apparatus as set forth in claim 13 wherein a friction member engages said first and second portions of said damper to resist relative movement between said first and second portions. 15. An apparatus as set forth in claim 14 wherein said first portion extends into an opening in said second portion, said first and second portions being coaxial and rotating relative to each other when said vent valve moves between the closed condition and the open condition. 16. An apparatus as set forth in claim 15 wherein said first and second portions are coaxial with a hinge of said vent valve. 17. An apparatus as set forth in claim 16 wherein an O-ring engages said first and second portions to resist relative rotation between said first and second portions. 18. An apparatus as set forth in claim 13 wherein said first portion is a shaft rotatable with said vent valve relative to said base, said second portion extending from said base into engagement with said shaft. 19. An apparatus as set forth in claim 1 wherein one of said vent valve and a base includes a magnet and the other of said vent valve and said base includes a magnetic material, said magnet applying a magnetic force to said magnetic material to move said vent valve relative to said base toward the closed condition. 20. An apparatus as set forth in claim 1 wherein a spring urges said vent valve toward the closed condition, said spring having a first portion engaging the vent valve and a second portion engaging a base. 21. An apparatus as set forth in claim 20 wherein said spring is a leaf spring. 22. An apparatus as set forth in claim 21 wherein said vent valve has pins extending through openings in the leaf spring. 23. An apparatus as set forth in claim 20 wherein said first portion of said spring extends into a recess in said vent valve. 24. An apparatus as set forth in claim 2, wherein the actuating assembly includes a force transmitting member secured to the plunger and the vent valve such that movement of the plunger from the first position to the second position pulls the force transmitting member such that the vent valve pivots from the closed condition to the open condition. 25. An apparatus as set forth in claim 24, wherein the force transmitting member is a flexible cable. 26. An apparatus as set forth in claim 2, wherein the force transmitting member moves with the vent valve to move the vent valve from the closed condition to the open condition, the force transmitting member moving relative to the vent valve to release the vent valve and allow the vent valve to move from the open condition to the closed condition. 27. An apparatus as set forth in claim 1, wherein the actuator assembly includes a force transmitting member having a first end section extending into a slot in the vent valve having a longitudinal axis, the first end section moving with the vent valve to move the vent valve from the closed condition to the open condition, the first end section sliding along the longitudinal axis of the slot relative to the vent valve to allow the vent valve to move from the open condition to the closed condition. 28. An apparatus which prevents objectionable increases in air pressure in a passenger compartment of a vehicle upon closing of a door of the vehicle, the apparatus comprising: a vent valve movable between a closed condition blocking air flow through a vent opening and an open condition enabling air to flow through the vent opening, the vent valve including a slot extending along a longitudinal axis;a door position sensor assembly operable from a first condition to a second condition in response to movement of the door of the vehicle from a closed position to an open position, the door position sensor assembly being operable from the second condition to the first condition in response to movement of the door of the vehicle from the open position to the closed position; andan actuator assembly connected with the door position sensor assembly and including a force transmitting member with a first end section extending into the slot of the vent valve, the first end section moving in a first direction along the axis of the slot and operating the vent valve from the closed condition to the open condition upon operation of the door position sensor assembly from the first condition to the second condition, the first end section moving relative to the vent valve in a second direction along the axis of the slot opposite the first direction to release the vent valve for movement relative to the actuator assembly from the open condition to the closed condition upon operation of the door position sensor assembly from the second condition to the first condition.
