    When all the doors are closed my door ajar light comes on, but it only happens when it is cold outside. Below freezing cold. when it warms up it doesn't do it.

    The door ajar light keeps coming on, the door locks are clicking on/off, etc.

I had a friend show me a trick that fixed this. Get some WD-40 and spary it where the door latches closed.... Open and close it a few times. Spray more if needed. It cleaned it off and the light stopped coming on.

Check the sensors on the body of the car, it's possible that one of the is broken or stuck. You can close all the doors but one, press the sensor & see if the display is gone, do this on every door till you find the sensor that is giving you trouble,

Good luck,

1999 mercury villager interior light won't go off.

If the door adjar light is on than you have a bad door switch. They are part of the door latch assembly. It is more common for the drivers side to go bad but it could be anny of them. A scan tool would be helpful in narrowing down which one it is. What you can try is spraying carb or brake cleaner into the part of the door that holds the door shut (the latch). Spray it into every nook and crany in that area. Open and close the door several times will a serving the door adjar light. If it goes out problem solved. If it doesn't go out get it scanned to see which one has failed and then pull that door pannel to inspect. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

I can not get my interior lights to tiern off the ones with the timer on them they stay on for 30 mints,after the car is looked and when driving they do not turn off.

Make sure you have your doors securely shut.Probably you would see a `door ajar' light if you didn't get them shut all the way? Just a thought,but probably not much help.Sorry... don-ohio
