    I have repeatly pushed the door button in and out to see if it was sticking and no luck. I have flipped the switches up on the mirror to see if that was it, but again no luck. I did notice when I position the switches between the off and on position they go off. What that means I have no clue?

Is the courtsey lamp knob turned on?

If not, it sounds like a bad door switch, courtesy light switch, or shorted wiring. Open the driver's side door and locate the door switch, it is usually near the hinges somewhere. Examine the switch and too see if any parts appear broken or snapped off. Rapidly push the switch in and out a few times and see if it has any effect on the lamp. Do the same with the passenger door switch. Also try rapidly turning the courtsy light switch knob on and off.

If you don't notice anything, you can try removing the switches and testing it with a multi meter or continuity meter. Both of these tools are available at an auto parts store if you do not own one. Let me know if you need help removing and testing the switch.

    Is it a on-off-door type switch (3 positions), or just on-door(2 positions)? I'm not too familiar with the switches on the convertible, let me know what the switch is labeled as. Have you checked the headlamp knob? It should be rotated counter clockwise to turn the dome lamps off in coupe models, try toggling this switch back and forth a few times.

    It sounds like you will need to remove these switches and test their function with a meter.

My interior light won't come on in my 1999 Buick Lesabre. I have checked the bulb & the fuse. Can anyone help me with this problem? Any ideas are sincerely appreciated.


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.
Body Control Module (MALL) Diagnostic Mode
For a detailed explanation of the MALL module diagnostic mode, refer to Body Control Module Cell 51.

Courtesy lights stay on all the time, only go out by pulling fuse


do you have the light switch on? also there is a little switch on the door that gets pressed when you close it this part could be broken causing the car to think the door has been left open thus leaving on the courtesy lights

What controls the inside interior lights


Voltage to the coil of the courtesy lamp relay, dome, reading lamp, courtesy lamps, cargo Lamp, instrument panel (IP) compartment lamp and the underhood lamp is supplied from the Inadvertent power relay on CKT 1732. The inadvertent power relay receives voltage from the CTSY LP fuse which is hot at all times. Ground for the courtesy lamps goes through the courtesy lamp relay. Both relays are controlled by the body control module (BCM) based on inputs from door jamb switch, dome lamp switch or door handle switch. The BCM will supply a ground to the courtesy lamp relay when closing any one of the above switches to ground. Ground for the reading lamp, cargo lamp, IP compartment lamp and the underhood lamp is supplied by its own ground.

Interior lights


This is both a courtesy and safety issue on many high end vehicles. The light from the interior lights can cast enough light to get to front door and possibly show dangers in your path. And after first getting into you car and starting it, you can check the back seat for any unwanted hitchhikers. As for the 10 minute timer, I don't know if this can be adjusted. A Chiltons/Haynes repair manual for you car may have that answer, or, the Buick dealership shop foreman. Best of luck.

2004 yukon slt courtesy light relay location


Here is a description of the courtesy lights , there is no relay ! Controlled by the BCM - body control module !
The courtesy/illuminated entry lamps, may be manually turned on or off by placing the interior lamp switch in the ON or OFF position. If an outside door handle is lifted or a door is opened, the courtesy/illuminated entry lamps illuminate. After all the doors have been closed the courtesy/illuminated entry lamps will remain illuminated approximately 15 seconds. The courtesy/illuminated entry lamps will also turn on prior to any door being opened, and remain illuminated approximately 40 seconds when the driver removes the ignition key. When the driver places the dome lamp defeat switch in the OFF position, the courtesy/illuminated entry lamps will be disabled.
The left and right front door courtesy lamps are controlled, and receive voltage and ground from the drivers door module (DDM) and the passenger door module (PDM) respectively. The body control module (BCM), DDM, and the PDM communicate through class 2 serial data for the lamp illumination commands and the door ajar switches.
The remaining courtesy lamps are controlled and receive voltage from the BCM. Voltage for the courtesy lamp supply voltage circuit and the backup lamp supply voltage circuit is from the TBC B fuse in the instrument panel fuse block directly through the BCM to these circuits. A short to ground on either of these circuits will open the fuse. Ground is provided to the footwell lamps and all courtesy/reading lamps at G203. Ground is provided to the right middle and right rear door at G306. Ground is provided to the left middle and left rear door at G302.

Courtesy lights stay on after the door has been closed on my 98 LeSabre. What is the cause of that and can I remove the fuse to get the lights off so the battery isn't drained?


Hi Dennis,

Your courtesy lights are controlled by your Body Control Module (BCM). Normal operation is for the courtesy lights to stay on for 2-3 minutes after the door is closed, then turn off.If they stay on longer than about 3 minutes, then there are several possible causes:

1. You may have the "courtesy lamp override switch" in the overide position in the dimmer control on the dash.

2. you may have a door that is not completely closed. You need to check ALL of them.

3. You could have a defective door switch or dimmer control switch

4. you could have a short to ground in one of the door control switch circuits, causing the BCM to "think" that there is a door open.

The CORRECT way to fix this would be to scan your BCM for fault codes and also read the BCM data to find out if it is showing one of the doors as being open when they clearly are not, so you will know which door is causing the problem.

Removing the courtesy lamp fuse will NOT completely fix the battery drain problem if these circuits are shorted or malfunctioning because the BCM will STILL be "trying" to turn these lights on and this will also cause an excessive draw on your battery. However, removing the 15 Amp fuse marked "CTSY LMP/MIRROR" located in the instrument panel fuse block will get the lights turned off and at least slow down how fast your battery is draining.
