Interior light work when you turn them to the on position but won't go out when you put the setting on door. The doors are closed but the lights never go out.

Courtesy Lights
The courtesy lights come on under the following conditions:
?€¢
Any door is opened.

?€¢
The interior lamp switch is in the ON position.

?€¢
The keyless entry transmitter unlocks the doors (illuminated entry).

When the key is removed from the ignition switch with all of the doors closed, the courtesy lights light for approximately 25 seconds before fading out.
Battery positive voltage (B+) is applied at all times through the IP fuse block CTSY LP/PWR MIR fuse 6A via CKT 640 (ORN) through the body control module (MALL) to the courtesy lights via CKT 1732 (ORN). The MALL provides a ground through CKT 156 (WHT) for the courtesy lights under the following conditions:
?€¢
The MALL receives an input from a door being opened.

?€¢
The MALL receives an input from the interior lamp being turned ON.

?€¢
The MALL receives an input from the doors being unlocked using the keyless entry transmitter.

The courtesy lamps then light.
When the courtesy lights are activated by opening and closing a door, the courtesy lights will remain on for approximately 25 seconds before fading out after all of the doors are closed. If the ignition switch is turned to START or RUN within the 25 seconds, the lights immediately begin to fade out. If a door is left open, the MALL removes battery positive voltage (B+) to the courtesy lights after 10 minutes. When the courtesy lights are activated by the interior lamp switch, the lights remain on as long as the interior lamp switch is in the ON position. When the courtesy lights are activated by unlocking the doors using the keyless entry transmitter, the lights remain on for approximately 40 seconds. If the doors are locked using the keyless entry transmitter within the 40 seconds, the lights immediately begin to fade out.

What interior light ? Dome , courtesy lights etc....They don't work with switch, keyless entry , door opening ?
What

Well, take it back to them as soon as possible. In the mean time check the light switch at the interior light which usually has three settings - "off" at all times - "on" when any door opens - "on" at all times. Try the different switch positions by getting in the car with all doors closed. One setting should switch the light on with the doors initially closed and will remain on even if the doors are then opened or closed. Second setting will be light off with doors are closed but light on when a any door is opened. Third will remain switched off even if any door is opened or closed. If the light can be switched off at one setting but remains on at the two other settings there is a malfunctioning micro switch at one doors. Look for the micro in each of the door frames (not door) and press each it a few times with your finger - if it is stuck it may come loose and work again. Try the switch's settings again. If it doesn't solve the problem either one of the door micros or the light switch may be defective and need to be replaced. Unfortunately this can only be determined by using a multimeter and should be done by a auto electrician or knowledgeable person.

Most cars have an interior light switch that works in conjunction with the dash panel light dimmer. When in it's extreme position, it turns on the interior light. Another possibility is a faulty door switch. I hope this helps you. Let me know.

have you set the light switch to the courtesy light position , with the ignition on turn light switch so light is on then turn switch so light is off ,open door if light comes on that is the courtesy position if does not close door turn switch to the last position then open door light should be on close door light off,TURN IGN OFF EXIT AN LOCK VEHICLE INTERIOR LIGHTS WILL STAY ON FOR A FEW SECONDS THEN SLOWLY DIM .watch them before leaving

There should be a switch on the overhead light that you can switch from off to door to on. If in the off position it overrides the lights. In the door setting they will come on when the doors are open. The on position will stay on all of the time.

The opening and closing by itself is either the door being out of alignment or the Door pin being worn and in need of replacement. As far as the interior lights staying on, look for the brightness control for the dashboard lights. If that is turned all the way to the brightest setting there is a position just past that which turns the interior lights on continuous. Make sure it is not in that position. If it is not in that position and the lights are staying on with all doors closed, to include the rears, and you have checked the switch on the dome light itself to make sure it isn't set to ON, then the problem is a switch in one of the door jams being grounded or a wire was tapped into the power circuit for the dome light that has grounded. This happens when the LoJack installer or Alarm installer makes the mistake of tapping the light circuit for power.

either the lights are turned on manually from the headlight/interior light switch, or you have a defective door switch that is telling the module that a door is open, or you have a door that is open, or your module that controls the interior lights is defective. I would start with the simple things, I would make sure all doors are closed. If they are, then check the headlight/interior switch to make sure the interior lights are in the off position, then check all of the door switches. They are simple normally closed push button switches that should be mounted on the car frame near the door hinges.

the switch has 3 positions on/off/doors.....there is also a timer for the doors/ignition,so with the doors closed try to find the on,then the off then you know the last position must be the doors......

Hi

Make sure all door switches are functioning properly. See that each switch pushes in and out, without sticking.
