I would ask a clarification request but it can't be done for this format. Anyway. Does the car have any type of aftermarket add on? Alarm, remote car start?
The Bonneville has a very sensitive electrical system. If there is an add on device there's a possibility that it has failed. There's more to installing an aftermarket device in a Bonneville than a simple install in a 'normal' car.
Another thing to check is the trunk and hood lights/switches. It's possible that the switch is broken or failed and is causing you the problems. Check to be sure that the trunk light and under hood light turns off when closed. They do take quite a beating over time.
Hope that helps.

    Generally check the switches on the door latch that control the dome lights.

Dome lights won't work on my 2005 Chevy equinox


The courtesy lamp supply voltage circuit of the body control module (BCM) supplies battery positive voltage to the dome lamp, the liftgate lamps, and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps with the switch in the AUTO position. The interior lamps receive a ground at G401 with the switch in the ON position.
The following lamps may be manually turned ON by placing the interior lamp switch in the ON position, or by opening a door while the switch is in the AUTO position.
?€¢
The dome lamp


?€¢
The liftgate lamps


?€¢
Courtesy/map lights


You can't turn them on manually ?
This could be a BCM problem , this best left to a ASE certified repair shop or the dealer .

I have a 2004 Silverado and when I open the passage door none of the inside lights come on but the drivers side does please help


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 II 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.
There could be a DTC - diagnostic trouble code stored in the BCM
DTC B2615
The body control module (BCM) receives a ground signal from the door jamb, liftglass/liftgate if equipped, or courtesy lamp switches requesting courtesy/dome lamp illumination. When this occurs, the BCM directly sends a voltage through the courtesy lamp supply voltage circuit illuminating the courtesy/dome lamps.
Voltage for the courtesy lamp supply voltage circuit as well as the backup lamp supply voltage circuit is from the left instrument panel fuse block TBC 2B 15-amp fuse directly through the BCM to these circuits
DTC B3801
The body control module (BCM) monitors the courtesy lamp switch signal circuit in order to determine when the courtesy/dome lamps should be illuminated. When the BCM senses that the courtesy lamp switch signal circuit is grounded when the switch is activated, the BCM will illuminate the courtesy/dome lamps.
Inspect the following related body control module (BCM), driver door module (DDM), and passenger door module (PDM) data parameters. Refer to Scan Tool Data List or Scan Tool Data Definitions for typical values and definitions:
?€¢
The courtesy lamp switch


?€¢
The interior lamp defeat switch


?€¢
The door ajar switches

Can't get dome lights on when door is opener even with override switch off?


The following lamps may be manually turned ON by placing the interior lamp switch in the ON position, or by opening a door while the switch is in the AUTO position.
?€¢
The dome lamp


?€¢
The liftgate lamps


?€¢
Courtesy/map lights

The courtesy lamp supply voltage circuit of the body control module (BCM) supplies battery positive voltage to the dome lamp, the liftgate lamps, and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps with the switch in the AUTO position. The interior lamps receive a ground at G401 with the switch in the ON position.
Important: If the liftgate is opened after all the modules go to sleep, the dome light will not come on. The liftgate ajar switch input to the BCM will not wake up the BCM once it has gone to sleep, so the dome light will not come on. Once the BCM gets an input to wake it up, from remote keyless entry (RKE) or a door handle, the dome light will turn on when the liftgate is opened.
If the driver inadvertently leaves any interior lamp ON, the BCM will turn it OFF after a 20 minute time-out.
The courtesy lamps will turn OFF immediately if the ignition switch is turned to the ON position or approximately 20 seconds after all doors are closed.
The courtesy lamps are controlled by the body control module (BCM). Inputs from the dome lamp switch and the door ajar switches are monitored by the BCM. When a door ajar switch is closed, or the dome lamp switch is turned to the ON position, the BCM supplies the B+ for the courtesy lamps.
With out a factory Tech2 scan tool or equivalent an knowing how these systems work ,you best bet is to take your vehicle to the dealer or some other ASE certified repair shop !

Interior lights not working


You mite have a DTC - diagnostic trouble code stored in the BCM - body control module , The BCM controls the interior lights ! Have you heard of a BCM ?
DTC B2615
The body control module (BCM) receives a ground signal from the door jamb, liftglass/liftgate, or courtesy lamp switches requesting courtesy/dome lamp illumination. When this occurs, the BCM directly sends a voltage through the courtesy lamp supply voltage circuit illuminating the courtesy/dome lamps.
Conditions for Setting the DTC
?€¢
When the BCM receives a courtesy lamp illumination request signal and the courtesy lamp supply voltage circuit is shorted to ground.

?€¢
When the BCM is not receiving a courtesy lamp illumination request signal and the courtesy lamp supply voltage circuit is shorted to voltage or open only to the first splice from the BCM.

?€¢
There is a loss of the rear fuse block TBC 3 battery supply voltage to the BCM for more than 1 second

Diagnostic Aids
?€¢
Perform a visual inspection for loose or poor connections at all related components. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.

?€¢
Only an open circuit up to the first splice from the BCM will set DTC B2615.

DTC B3801
The body control module (BCM) monitors the courtesy lamp switch signal circuit in order to determine when the courtesy/dome lamps should be illuminated. When the BCM senses that the courtesy lamp switch signal circuit is grounded when the switch is activated, the BCM will directly illuminate the courtesy/dome lamps. Do you know what a scan tool is ? not a code reader !

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.

My sister has a 2000 chevy cavalier b4 the door chime and the interior dome light worked now they both dont, we replaced the bulb and fuse to no avail and I have no clue what's wrong with the chime.


the chime actually is done with the radio. the front drivers door speaker. so if the radio works and the front left speaker works. then more then likely you have a defective door switch. located in the door jam that controls the dome light

2003 ford explorer driver side door opens and closes by itself and interior lights stay on while driving


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.

Dome lights won't turn off


Been having a problem with the dome lights on a 99 chevy blazer. Still can't figure out what the problem is. There is a dome light overide button located under the dimmer wheel. When I push the overide button in the dome light goes off, but when I open any of the doors the dome light will not come on. When the overide button is out the dome light stays on all the time and will not turn off even though every door is closed. I checked all the pushbuttons and everything tests good. Has anyone had this problem and know how to fix it?
