Question: 1999 Mercury Sable mileage: 77,000. My interior lights and the " door ajar" light is on all the time while I‘m driving. The Dome light will stay on 30-40 minutes after the car is turned off. In addition, the drive’s door will not lock or unlock by the power lock system. I am guessing these problems are tied in together. The doors are not ajar, so I’m thinking there is something wrong with the sensor. Please help. Thanks.
Hi, the two problems may not be related, the door ajar switch is faulty, it is actually in the door latch assembly, the lock problem may be a door lock actuator inside the door panel, usually you can hear it if you listen close but it will not move the lock
