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.

My dome lights mirrors or door locks want work if i have my door cloosed but if i turn dome light switch all the way on with door open it all works if i cut my dome light switch off with doors open mirrors...


It's some kind of short. my guess either the wiring in the boot between the door itself and the frame/ body. or possibly in the circuit for the door courtesy switch, lastly the dome light circuit. if you have a test light, probe for a faulty circuit (grounding or incomplete)

Door jamb switch


all doors there are drivers, and then OTHERS, (wiring)
its wired OR logic, so any switch grounds, it turns them on.
and is programmable on all cars. to have this on or off (features explained in the operators guide, lost that?)

CRV has 3 lamps
front dome
rear dome
and spots.
all of them are messed up? for all doors.
if yes, ITS programming. is wrong.

the rear light is directly controlled lamp to rear lamp. (hatch glass or gate switches.
and has a slide switch, off,on, auto.
the spots lamps are direct. on, or off
the front however is totally different and wired unique.
as you know the drivers door is unique, as it operates the
keys left in igntion, or head lights left on, mode. so if those work
right then the drivers door switch, is,, working......
the front dome
has 3 modes. again , off , on and auto .
Auto is the MCU , unit, the MCU sees any door open and the front dome gets input to the AUTO pin, and if in auto the lamp glows.
i dont think the MCU is programmable but do read the oper guide for that., i dont have one.

How do turn on the light inside the sunfire aside from those reading lights on the rear view mirror?


  • There is a dome light switch on the dash. Turn it all the way to the right and it will click. Torn it to the left to turn the dome light off.

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

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.
