Try to scan the lightning control module from faults memored using a diagnostic scantool connected to the data link connector of the car. Try to erase all errors from lightning control module memory, in order to reset the lightning control module. The last component out of order is the lightning control module.

You will have to take out the door ajar switch. It is located in the door. This works your interior lights and door ajar switch which is in the door and is hitched to the door latch. Spray the door latch with WD-40 and open and close the door a few times, and then spray again. If this does not work then you will need to replace the driver's door module and/or the light control module.

2002 lincoln towncar door ajar light s stay on after minor accident. Only goes off when in drive. Can't find the fuse. I have to disconnect the battery

You have one or more door ajar sensor switches that are defective, have the BCM (Body control module) scanned to see which door is causing it, the light can be turned on by any of the 4 doors. The sensor is located inside the door on the door latch mechanism, there is no fuse as it is a ground circuit.

Auto door lock don't work, they click when activated. Also the door ajar light stays on and auto light does not work. F350 super duty 2002 ford

You might need to oil the locks. Our truck does that some times. We just spray some WD40 on the catches and keep clicking them back and forth till it sinks it. As for the ajar light, the sensor inside of the door jam might be damaged. or the switch on the lights is turned on. I did that once.

Door alarm comes on while driving.

This is caused by a defective door ajar switch in one of the 4 doors. The switch is located on the back of the door latch mechanism inside the door. The system can be tested to id the defective switch which is far better than just removing all 4 door panels and rear glass channels to access the 4 switches. Each switch is about $15.00 time to remove them about 4-5 hours for all doors to do this the hard way.

I got a mercury.. and the problem is the driver door some time it locks good all the way while start driving will lock, just like any other car. and some times it wont lock u can still drive but it will...

Your door ajar switches are located inside the rear faces of each door along with the latches. Just liberally spray a petroleum based lubricant into the door latch areas of each door (one at a time) and open / close the door several times. Once lubricated, your door ajar light, interior lights, and autolocks should function properly.

Good luck.
