It's the vacum pump in the trunk. sometimes it's just the connectors sometimes the pump itself. The whole system is vacum acctuated. -

my door locks and trunk won't work, but the doors will close with the vaccum assist. Also, the inside door lock switch on the center console won't work, the switch usually flashes when you lock or unlock it. -
