My 2006 Ford F150 driver side door sensor is not working. When I open the driver side door the interior light does not go on, and there is no warning sound to notify me that my lights are still on or the keys are still in the ignition. When the passenger door is opened the interior light does go on. Any suggestions on how to fix it my self?

The above suggestion is half assed and explains why we get such poor service from Steelerships. The Ford/Mopar sensor is a two piece unit that should be removed entirely from the door lock, opened in half, and cleaned with electrical contact cleaner and blown out with air in the bottom electrical section, and lubed with white lithium grease in the top section (above the thin rubber cover in the top). Before re-installing the door lock system and buttoning up the door, make sure and fully test the sensor: 1) once all the electrical connections are reconnected, press down on the swich (simulating the door opening). The light should come on, and if the keys are in the ignition, the "key in the ignitiion" chime should sound. 2) Inspect the little locking tab which locks the sensor into the door lock; it should look like half of an arrowhead (half a triangle), with a flat bottom. If the bottom has been ground away (upward), it is likely the cause of the problem, as it will no longer correctly maintain proper alignment in the door lock (replace). The part number for the 2004-2008 F150 is : 4L3T-10B997-AE, also sold as part number SW6129. The above suggestion is half assed and explains why we get such poor service from Steelerships.
