Rear fuse box. INT LP 10 amp . there is also INT LP relay in the same rear fuse box .
Fuse Block - Rear
Under the rear seat, on the left side of the floor pan
The INT LP fuse in the fuse block - rear supplies battery positive voltage to the normally open switch contacts of the INT LP relay. The INT LP fuse also supplies battery positive voltage to the INT LP relay control circuit. The fuse block - rear also supplies battery positive voltage to the relay control circuit for the front courtesy lamp. The door modules communicate on a simple bus interface (SBI). When you open any door, the switch contacts of the door open switch close. When a door open signal circuit is grounded, that door module sends a message to the drivers door module (DDM) in order to indicate that a door is open. The DDM sends a class 2 message to the rear integration module (RIM) in order to indicate which door is open. The RIM activates the INT LP relay in order to provide battery positive voltage to the interior courtesy lamps. When any front door is opened, the RIM will energize the FRT CTSY lamp relay grounding the I/Pcourtsey lamps at G302. Depending on which doors are opened, front or rear, the proper interior courtesy lamps illuminate. The RIM provides a pulse width modulated ground to all interior courtesy lamps for the interior lights theater dimming feature. Some of the courtesy lamps are also used as reading lamps, each reading lamp may be manually turned on or off using it's own respective switch
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.
you will probably find that the small spring at the hinge to open the door when the release is activated has broken
try with the help of a friend activating the release to open the door manually
otherwise you may have to go in through the boot, remove trim and undo the latch bolts to allow the latch to let the door open
all the lights above the dash do not work ?????? DOME light's ??? No light's come on when you open the door or any door ? Wouldn't think all the door ajar switches bad at one time .
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This Includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Auxiliary dome lamp (SEO, RPO 6C7)
• Dome lamp
• instrument panel (I/P) compartment lamp
• Inside rear view mirror lamps
• I/P courtesy lamps
• Reading lamps
• Rear compartment courtesy lamp
• Sunshade vanity mirror lamps
Battery positive voltage is applied at all times to the DIC/RKE fuse and to the switched side of the BATT RUNDOWN PROTECTION relay in the right I/P junction block. The DIC/RKE fuse supplies battery positive voltage to the coil side of the BATT RUNDOWN PROTECTION relay. When the ignition is turned to the ON position, the body control module (BCM) provides a ground to the Inadvertent relay control circuit. This energizes the BATT RUNDOWN PROTECTION relay and applies battery positive voltage to I/P BRP fuse and to the TRK/ROOF/BRP fuse. Battery positive voltage is applied from the I/P BRP fuse to the I/P courtesy lamps, I/P compartment lamp and to the I/P compartment feed circuit to the BCM. Battery positive voltage is also applied from the TRK/ROOF/BRP fuse to the:
If the BCM receives a door lock or unlock input signal, the BCM will activate the BATT RUNDOWN PROTECTION relay, which provides battery positive voltage to all interior courtesy lamps. When any door is opened, the door jam switch contacts close and the BCM receives a door-open input signal. The BCM then applies a ground to the theater dimming ground control circuit illuminating the courtesy and dome lamps.
After all the doors are closed, the courtesy lamps remain illuminated for approximately 40 seconds. The courtesy lamps will also turn on and remain illuminated for approximately 15 seconds after the ignition key is removed, prior to any door being opened.
When the headlamp switch is placed in the DOME position, the BCM receives a ground signal. The BCM then applies a ground to the theater dimming ground control circuit. This illuminates the dome and roof rail lamps.
The courtesy lamps will normally turn off using the theater dimming feature. The BCM provides a pulse width modulated ground to all courtesy/reading, dome, and inside rear view mirror lamps for the theater dimming feature. The BCM will immediately turn off the courtesy lamps if a door lock command is received with all the doors closed, or if the ignition switch is turned to either the ON or RUN position.
The BCM activates the interior lighting output 15 seconds after receiving the class 2 message "Airbags Deployed" from the sensing and diagnostic module (SDM). The interior lamps remain activated for 25 minutes.
The door ajar switch is part of the lock actuator inside the door !
open the door interior light will be on put the vehicle ignition in run postion dash lights will be on operate the window switch up and down look at dome light if it is dimming a little when operating switch window motor is no good if not remove the switch and check power at switch if none the boot between the body and door has a broken wire
Door left open chime is operated by your interior light switch. It is located in a few places on different vehicles. Often in the door jam at the front or low down on the pillar at the rear of the door. You will notice a little black rubber boot and when you push it it goes in and out. That is your interior light switch.
You have a current draw somewhere. Often times glove box light, radio, trunk light. These things you can't see because when you open them light comes on anyway. There is another method, it sucks. Take keys out of car. Turn every thing off. Close all doors and trunk. Open the hood, if you have a hood light, unplug it. Remove the negative battery cable from the battery. Place a test light between them. Clamp one end to the negative battery post and the other end to the disconnected negative battery cable so that there is still a connection but ONLY through the test light. Your test light should be lit up, this shows you a draw. Now if you have a fuse box under the hood, pull the fuses out one at a time keeping an eye on the test light. After pulling the fuse out and watching for the light to change, put that fuse back in and move to the next one. A very slightly noticeable dim is ok, what you are looking for is a big drop in the brightness in the light. This will indicate the largest draw. If you don't notice a large drop in brightness here, go inside the car and close the door once you are in. The door can not be open because that tells the dome light to come on and that will give you a false draw. Now while you are in and everything still off and all doors closed crawl underneath and and pull out the fuses inside there too just as you did for the other fuse box. If you get that fairly significant dim on your test light by pulling a fuse, THAT is the circuit that has the draw. Look to see what that fuse goes to and that narrows it down drastically. Good luck!
possible broken wire in loom between door and a pillar, open door and at front end you will see rubber boot peel this back and gently tug wires one at time normally red or black thick guage wire breaks carry out repair and should fix problems
Try removing one bulb or the other at one time preventing power completing the circuit if the problem in a light. Those ones are tuff to find but second place I would start is removing front door cils and cleaning out and playing with wires in there to see if you can find a problem, also wires in the boot between door and frame, usually drivers side cause it's used more often.
the door ajar switch in the drivers door latch is is either shot or sticking.open drivers door spray some WD40 in the latch,open and close door several times and if the switch is only sticking this will free it up.
