The dome light gets 12 volt battery power at all times. The door switch, when the door is opened, allows the current to flow to ground, and completes the circuit. The door switch allows the ground to be made. Measure for 12 volts at the wiring connector, and measure for direct short at the ground wire, with the door open. The Ground wire is white with a black tracer.

Dome light will not go out


Are you having any other weird electrical problems like, stereo door speaker not working or power window or door lock not working? If you are it may be a bare wire in the door wiring. That is a common problem on 2004 Rams. Normally it is a rear door if it is a quad cab. Short is normally in the boot going from the door to the cab. If not then the problem is probably the dome light switch found on each door. I believe it is in the door handle and each one would have to be tested.

I would consult a repair shop or buy the service manual and look through the wiring diagrams. If you can't read wiring diagrams and have no testing equipment then it is best left to a repair facility.

Interior Lamps
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 !

Dome light now working on a 2011 enclave. i looked at dome switch. what do i need to do?


Hello! If you have a multimeter and a little experience using it I'll send a very easy test procedure...If you do not have a meter send a comment...Remove the lens cover from the dome light...You'll see two wires...Orange and Black...Set the meter to read 12 volts...With the drivers door open Read across the Orange and Black wires with the dome switch off...If you do not read 12 volts the door switch is bad...
If you do read 12 volts turn the dome switch to on...if the bulb is good...The dome light switch is defective...But I doubt you will read 12 volts on the Orange wire to ground...More then likely the door switch is defective...Gently pry the door panel off...Use a screw driver with shrink tubing over the tip...
The wire colors on the switch are Tan and Yellow...It is a part of the latch assembly...You can replace it yourself, however since it's a 2011 its a warranty item...On the difficulty scale of 1 to 10 replacing the door switch is a 4...Guru.......Saailer

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.

I have a 2000 Pontiac Grand Am and the interior stay on


Interior Lights Circuit Description
By using a feature called inadvertent power control, the body control module (BCM) supplies power to all of the following components:
• The courtesy lamps
• The dome lamps
• The rear view mirror reading lamps
• The instrument panel compartment lamp
• The rear compartment lamp
The left front door ajar switch turns the interior lamps on through the BCM by grounding CKT 394. When the left front door is open, the switch is closed. This condition provides a ground and a door open input to the BCM. The BCM then grounds the following lamps through CKT 156 in order to turn the lamps on:
• The courtesy lamps
• The dome lamp
• The rearview mirror lamps
The right front door ajar switch and the rear door ajar switches turn the interior lamps on by grounding CKT 395 from the BCM.
When the ignition key is removed from the lock cylinder, the interior lamps remain on for approximately 40 seconds.
The BCM provides an interior lamps-on delay after a door is opened. The lamps remain on for approximately 40 seconds or until the ignition switch is turned to the ON position. The 40 second lamps-on delay reduces to 4 seconds if a door is opened within 2 minutes of the ignition switch being moved from the ON position. The interior lamps immediately turn off when the vehicle begins to move.
The dome lamp OFF-DOOR-ON switch controls the dome lamp. When the switch is in the OFF position, the dome lamp remains off. When the switch is in the DOOR position, the dome lamp lights when a door is opened by the BCM grounding CKT 156. When the switch is in the ON position, ground is supplied through CKT 750. The rear view mirror reading lamps are controlled by the rear view mirror reading lamps switch or through CKT 156 from the BCM.
Voltage is supplied at all times to the BCM through the INT LPS fuse. The BCM supplies voltage to the interior lamps through CKT 1732.

Battery Run Down Protection
When the ignition switch is in the OFF position, the BCM turns off the power to all of the interior lamps after 18-22 minutes.
The BCM will reset the inadvertent power control relay output when one of the following actions is performed:
• Open or close a door.
• Turn the ignition switch to the ON position.
• Turn off any interior lamps that may be on.
• Press the power door lock switch/keyfob button.
• Press the decklid release keyfob button.

Saturn Turn Signal / Dome Light Issues


The interior lamps system consists of 2 main features. Illuminated entry and a battery saver feature that will turn the interior lights off after 20 minutes if they are left On with all doors closed and the ignition Off. The body control module (BCM) controls both of these functions. Battery power is supplied by the BCM through CKT 1732 to the following lamps:
• The dome lamp
• The map lamps
• The rear reading lamps
• The rear dome lamp
• The cargo lamp
• The glove compartment lamp
• The courtesy lamps
• The sunshade lamps
The BCM also controls the ground circuit side of the dome lamp and reading lamps for illuminated entry. The dome lamp and reading lamp will remain on for 20 seconds after the ignition key is removed and the last door is closed. In addition, if the vehicle is equipped with remote keyless entry (RKE), the dome and reading lamps will turn On and stay on for 20 seconds after an UNLOCK signal is received from the keyless entry transmitter.
The reading lamps, dome lamp and map lamps can be turned On at any time by moving the appropriate switch to the On position.
The rear dome lamp is fed battery voltage through CKT 1732 from the BCM, through the liftgate ajar switch, and is grounded through CKT 650 to the rear ground splice pack. The rear dome lamp will turn on when the liftgate is opened. The cargo lamp is fed battery voltage through CKT 1732 from the BCM, through CKT 744 and grounded through the decklid ajar switch.
The courtesy lamps are fed battery power through CKT 1732 and are grounded through CKT 745-- left front, CKT 747--left rear, CKT 748--right rear, CKT 746--right front. These circuits will ground through the door jamb switches. The courtesy lamp will be illuminated when the affected door is opened. For example, when the right rear door is opened, the right rear door courtesy lamp will turn on.

Not a fuse problem , if the BCM had blown fuse other thing's wouldn't be working as well . . Probably wiring or BCM . Using factory diagnostic,s instead of guessing as to what the problem is , is the proper way .

Interior Lamps Diagnosis
Symptom
Procedure
Important: Before proceeding with these diagnostics, check for DTCs. If DTCs are present, complete the associated diagnostics. If the condition still exists, return to this chart.
All of the interior lamps are inoperative when any door is opened.
