Door ajar light won't go off

Principles of Operation
Interior Lighting The interior lighting is broken down into two groups: the courtesy lamps and the illuminated entry lamps. Both lighting features interact with the courtesy light arbitrator. The battery saver is also listed in this section.
Courtesy Lighting The courtesy lamps consist of the dome lamp and/or map lights. The courtesy lamps can be activated by the GEM using the panel dimmer switch, or by any ajar door. The courtesy lamps will shut off when the doors are closed and the illuminated entry feature is not active, or when the vehicle speed is greater than 8 kph (5 mph). The interior lamps will not be reactivated until the vehicle speed is less than 5 kph (3 mph) and a new door open warning lamp switch signal is received. The inputs are:

• ignition switch position

• driver door ajar switch

• front passenger door ajar switch

• rear left door ajar switch

• rear right door ajar switch

• vehicle speed switch (VSS)

The outputs are:

• battery saver relay

• interior lamp relay

Check the door switches, you may have one that's shorted. If they are all OK, the BCM is causing the problem. Easiest and cheapest solution is to remove the bulbs from the lights that are always on. It means they will not operate and if you don't feel safe at night without them, its not an option for you, If it doesn't bother you one way or the other, remove the bulbs. This will stop your battery from draining, but the door ajar light on the dash will stay on all the time. If it bothers you, cover it up!

That is normal operation, as long as the door is open the door ajar switch senses that and keeps the interior light(s) on.

A quick guess is that one of the power sliding doors is not closing properly or the switch for that door is broken. A broken door switch would leave the door motor or interior lights on continuously and drain the battery. Draining the battery more than a few times would ruin it. Also check the front door switches for broken or missing actuators - the door ajar icon looks similar to the sliding door open icon.

I tried to download an owner's manual so I could be sure I was interpreting your dashboard icon correctly, but the oldest one available is for 1999, so my information may not be accurate.

this problem is caused by a tiny micro switch that is attached to the door latch inside the doors, the stick and give this false warning, have replaced dozens of them, it is called the "door ajar" switch oddly enough :)

you have to take out the door ajar switch its in the door it works your interior lights and door ajar switch which is in the door and is hitched to the door latch

Take some WD40 and open the doors and spray a liberal amount into each of the door latches. Then open and close the doors firmly several times. This will work most of the time to unstick the ajar switches.

The door switch is stuck on or the wire is shorted to ground.

This is usually caused by the switches sticking in the door latches. Try spraying some WD40 in the latches and open and close the doors a bunch of times that should take care of it.

must be a break in the wiring somewhere and will not be a quick task to check unfortunately, sorry but you will probably need auto electrician unless you feel up to checking it all your self if so check the contacts with an auto probe to see where youhave feeds and where you have earths then check others till you see a break in the pattern or better still if you have or can get wiring diagram then follow it through.
