The door ajar light should come on when the door is opened. When the door is closed completely, the door ajar light should go off. You will notice that a new door ajar switch will seem longer than your old one. The first time that you close the door, its shaft should adjust to the proper length to be able to properly detect whether or not your door is closed completely.
If the switch isn't too worn, you can sometimes pull the shaft out to its full length again, and close the door to "readjust" it again. I've had this work a couple of times. If the switch is past its prime, then it will not stay at the proper length, and have to be replaced.
Sometimes you can also improvise by simply putting a rubber stop where the switch makes contact on the door, and that will allow the switch to operate the door ajar light properly. NCRS judges, however, won't be too fond of that solution.

So the door switch should turn the ajar light on if the switch is partially pressed?
.
No--when it is "not" depressed......when it is "released".
These switches are the ones closest to the rear of the car.
Some of the guys on the forum have said the aftermarket switches are not good...so buy the GM ones.I have been lucky to have had a supply of the GM ones so I havnt experienced the problem with the after market ones.

Unscrew the switch short the wires the light will go out (tape up the wires there HOT ) Go for a ride go around a corner If the light does not come on re-place the switch. Been there done that.
