2001 Mitsubishi Galant Dome light (reading / courtesy lamp)

Recently my dome light has been staying on draining my battery. I check all the fuses and all are working. I have check the actually switch and doesn't seem to be anything out of the ordinary there either. When I put the key in the ignition and turn the light will turn off but as soon as I turn to off the light comes back on. Any ideas would be appreciated.

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 .

No other lights on ,dome, courtesy etc...
Battery Rundown Protection/Inadvertent Power
In the event that any of the interior lamps supplied voltage by the inadvertent power relay and ground from the courtesy lamp relay were to remain on when the ignition is OFF after a period of 20 minutes, the BCM will deactivate the inadvertent power relay turning OFF all of the lamps on that circuit to prevent total battery discharge. Only when the ignition switch is cycled back to the RUN position will the BCM reset the internal timer and reactivate the inadvertent power relay. When the inadvertent power relay is not energized, the BCM utilizes the inadvertent power courtesy lamp supply voltage circuit to monitor for a courtesy lamp switch request signal. If a courtesy lamp switch is activated, the BCM will receive the signal to energize the inadvertent power relay by grounding the control circuit.

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.

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.

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

this could be a door switch problem or a BCM problem. access the BCM for codes and data this will help. check to make sure the headlight switch for the interior lights is in the off position.

No dome light


You shorted the interior lamps/or it is burned out. get the car manual and look for where the interior lamp fuse is located to check if its the fuse. IF all the courtesy lights on your doors are working, then your dome light bulb is burnt, check modifiedlife.com for the correct size bulb and order it from an online automotive lighting store for a fancy color or go to your local auto store for the standard bulbs they have available.

Cargo lamp on message stays on


Check under the hood, in the fusebox, for a fuse label ctsy (courtesy). It'll be over the driver side wheel. Replace it, if blows and, you have a wire touching bear metal somewhere. Good luck!
