Dome Light, Door Ajar, Door Locks - 5/13/2007 9:10:55 PM    Mike11C Posts: 28 Score: 0 Joined: 2/13/2007 Status: offline My wife's 99 Taurus SE (3.0 V-6, 90,000 miles) will sometimes act strange. The "door ajar" light and dome light will stay on while driving and the doors will not lock automatically. This does not happen all the time. If anyone knows why this is happening I would appreciate your help. Thanks. _____________________________ 2001 Ford F350 Super-Duty, 4x4, 7.3L Turbo Diesel, 4 Door, Long Bed There is no problem so great that it cannot be solved with a suitable application of HIGH EXPLOSIVES!

It's mounted/positioned with it's nose in the 'upwards' position in the lower door latch area.. It's not a sealed switch and the pin commonly sticks as debris/water collect on the spring loaded pin causing it to stick.. Most times with a little work you can get them unstuck with a light spray and some door closures as Use Common Sense noted..

I thought it was a door switch but, unlike older vehicles, it isn't visible inside the door jamb. This was confusing to me and I wasn't quite sure where else to look. I'll look inside the doors and clean/lube the actuators this weekend. Thanks again. _____________________________ 2001 Ford F350 Super-Duty, 4x4, 7.3L Turbo Diesel, 4 Door, Long Bed There is no problem so great that it cannot be solved with a suitable application of HIGH EXPLOSIVES!

Gravity will help get the lube where it needs to go ;) _____________________________ 05 F250 C/C FX4 6.0 1969 Firebird Trans Am 2003 Hayabusa GSXR1300 (in reply to Mike11C) Post #: 5

We were able to isolate which door was the problem, and were fortunate to still be under warrenty so the dealer replaced the sensor at no cost.  Actual cost of the sensor that went bad was $80.  Since then all is well. Good Luck! _____________________________ Mike & Catherine M. Richmond, VA 2002 24valve Taurus Wagon Sel 2002 Trooper 1977 F100 (in reply to Hayapower) Post #: 6
