I have a 2007 Buick Lucerne and the front reading lamps won't turn off.


Overhead Console Lamp and Roof Rail Courtesy/Reading Lamps
The courtesy/reading lamp is a duel purpose lamp that can be illuminated two different ways. First, the lamp can be turned ON during courtesy lamp operation as described above. Second, the lamps can be turned ON individually for reading lamp operation by the lamp switch. The BCM supplies battery voltage from the INT LAMPS fuse through the inadvertent power courtesy lamps circuit to the courtesy/reading lamps for reading lamp operation only. Ground for the courtesy lamp module or the roof/rail reading lamps is provided at G402

Courtesy Lamps
When either one of the front doors is opened, ground is applied through the door latch door open switch and the door open switch signal circuit to the door module indicting the door open position. In response to this signal, the door module sends a GMLAN serial data message to the BCM of the door open position. Or, when either one of the rear doors is opened, ground is applied through the door latch door open switch and the rear door open switch signal circuit to the BCM is indicating the rear door open position. Once a door open message or signal received, the BCM will then apply battery voltage from the CTSY/RF TRN fuse through the courtesy lamp supply voltage circuits illuminating the lamps listed below:
• Overhead console lamp
• Roof rail courtesy lamps
• Footwell courtesy lamps The BCM receives battery voltage from the INT LAMPS fuse in order to supply power to the inadvertent courtesy lamps. Inadvertent power courtesy lamp feature provides a similar function for the interior lamps as a retained accessory power feature. The BCM will energize the courtesy lamps supply voltage circuit when the BCM is in the active state (awake). When the inadvertent power courtesy lamps supply voltage circuit is energized, it supplies voltage to all the interior lights listed below. The BCM will continue to supply voltage to the interior lamps after the ignition is turned OFF so that the interior lamps may be operated.
• Overhead Console Reading Lamps
• Roof Rail Reading Lamps
• Vanity Mirror Lamps
• I/P Compartment Lamp
• Rear Compartment Courtesy Lamp
In the event that any of these lamps were to remain illuminated for a period of more than 20 minutes with the ignition switch in the OFF position and no BCM input activity, the BCM will deactivate the inadvertent power supply voltage circuit to prevent a total battery discharge condition. The BCM receives battery voltage from the CTSY/RF TRN fuse in order to supply power to the courtesy lamps. The BCM applies this voltage to the courtesy lamps through the courtesy lamp supply voltage circuits. When any door is opened, the door open switch contacts close and the BCM receives a door-open signal. If the BCM receives a door lock or unlock signal, the BCM will activate the courtesy lamp supply voltage circuit, providing battery voltage to the dome lamps and the left and right footwell courtesy lamps. The courtesy lamps can be manually activated by placing the interior lamp switch in the DOME position. For more detailed information concerning courtesy lamp operation refer to Interior Lighting Systems Description and Operation.

The right hand interior light on my Sportage has stopped working. The left hand one works but no the right hand


I believe there is a diode in the wiring to the bulb! Trace the wire and feel for a bump in wiring and check/replace diode!

What is the function of three buttons located between the two interior front dome lights in the 2006 honda pilot?


One button has one dot, the next has two dots, and the third has three dots? These are the "home link" buttons. They can be programmed to open your automatic garage door openers.

The rear cargo light won't turn off. This happened after I replaced a rear turn signal tail light bulb and a fuse for the horn. (These went out at the same time.) When the blinker light and horn were...


Hello! The instigator of this problem appears to be the the rear cargo lamp; Official name is rear dome light. You'll need a multimeter set on the X10 ohm scale to shoot this trouble. Leave the rear dome light bulb out. There are two switches involved; #1 the rear dome light on/off. #2 the right hand front door switch.

Pull the horn fuse out, remove the rear dome light cover, drop the rear dome light down to access the wiring and close all doors on the vehicle. Connect one lead of the ohm meter to the white wire and the other to body ground. If you read any resistance one or both of the two switches (dome light switch or right hand front door switch) is remaining closed when all doors are closed. Next disconnect the black lead from the dome light switch and see if reading changes to zero. If it does this is indicating that the dome light switch is defective. If it does not, disconnect the right hand door switch and take another reading at the same location. If you still measure any resistance, the black wire of the rear dome light is shorted to ground, if not then the right hand door switch is the culprit.

The reason the right hand door switch and not the left hand door switch is involved is the fact that opening the left front door would turn on the front dome light as well as the rear light. If both dome lights are staying on with all doors closed I would then involve both door switches in this test procedure. If your vehicle is a four door model then disconnect one door switch at a time while performing this test procedure.

The horn fuse also supplies power to the rear dome light, and I suspect the two events are related.

Interior lights won't turn on when door opens


you have a bad drivers door latch, the micro switch inside is not telling the computer that the latch has been opened which would normally mean the door is open.
