I just thought of a way to check it in the car. Open your door and verify that the light is on. Then from the outside, slowly close the door but not all of the way. Once you feel the latching mechanism touch the striker pin in the doorjam, gently press the door all the way closed with the palms of your hands until it barely engages. Look inside and see if the light is still on. You should to do this with the car running because the light will stay on anyway for a while until you start the car or the timer switches it off. Repeat on passenger side if this doesn't work. |
