SOURCE: 1999 Mercury Sable Dome Light won't shut off

Next to the headlight switch is a dimmer dial for the interior dash lights... if you turn it all the way up, the interior lights remain on... there is a "detent" on the dimmer. turn the interior dash lights all the way full on'll feel the detent, then turn it down back past the detent a little bit...that should cancel the interior courtesy lights... wait a bit because the interior lights are sometimes on delay timers....
good luck let me know what happens.

SOURCE: door ajar light, drivers door

Its on the pillar, part of the main body, not the door itself. Usually close or under where thedoor latch meets the stricker. It may have a small rubber boot on it (They do go bad, and are fairly cheap)

Dome light inside 2009 mercury marquis won't go off. What can I do?

Common Mercury problem, a sticking door ajar switch inside one of the door latches. Get you some WD40 and spray inside all the door latches making sure you use a good amount on each, operate each quite a bit, 5-10 times to let the WD40 work on each. This should take care of the problem. Repeat if you need to get results.

Ford uses a tiny micro switch that is mounted on the door latch inside the door to turn on the dome light and provide door ajar sensing, the switches get water in them and this causes them to not make a good connection, it is a very common problem, i have replaced dozens of them at my dealer. Have the switches tested by the dealer, they do it with a electronic system scanner that can ID which of the 4 door switches is acting up.

96 grand marquis... my interior lights (dome and doors) stay on after car is started and wont turn off until about 10 minutes after I stop the engine/turn the vehicle off. Doors seem fine (have not...

The first thing is that this car has an auto shut down, if it sees any lights on it shuts them down after a while, this is why they are shutting off, i think you are correct with the door switch, the most common one is the driverdoor switch, its a small push type switch on the latch asm as you know, i would start with the driverside door, i would almost bet thats the bad one, as afr as the headlight switch try unplugging it and see if light goes out but some models operate throught the switch but most dont so if its the dimmer switch then the light should go out when disconnected. good day.

Dome lights intermittently flash on and off in a 1996 Jeep

If it has automatic or a domelight that stays on for a while after you shut the door is on a timer relay and that is probably getting bad. As far as the door ajar message there is a switch in the door jam, look and see if you see it. Take wd40 and try to soak the switch try to get it inside the switch.If its incorporated in the door latch spray back inside the door latch real good. Open and close the door several times and see if it works then.
