Question about 2007 Saturn ION-2 Quad Coupe

Dome Light (switched circuit now working) Shorted it out

I shorted out the wires on the dome light on my 2007 Saturn ION (Installing a DVD player/screen).

The constant power is working, but the switched (the one that turns onwhen the door opens) is not working, there is no voltage on thatcircuit.

Where would I find the fuse for the switched dome light? (I've checkedall the fuses at the drivers foot area and they all look good)...Allother accessories appear to work, except noted below.

Also as a side note, not sure if it's related but after I tried allaccessories and locks and windows the rear window behind the driverwill not go down now, could this be related? I hear a click when I tryfrom the drivers console, but nothing when I try from the rear seat?

Why didn't you hook into the entertainment system (radio ) ?
The one that turns on when the door opens is controlled by the BCM -body control module .You probably shorted out the transistor in side the BCM .
These lamps may be manually turned on by placing the interior lamp switch in the ON position, or by opening a door.
• The Dome Lamp
• The Rear Compartment Courtesy Lamp
• The Rear View Mirror Map Lights
The inadvertent power control circuit of the BCM supplies battery positive voltage to the dome lamp 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. The interior lamps receive a ground at G401 or G403.
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 normally turn off using the theater dimming feature. The BCM provides a pulse width modulated ground to the interior lamps for the theater dimming feature. The courtesy lamps will also turn off immediately if a door lock command is received with all the doors closed, or if the ignition switch is turned to the ON position.

A door-closed switch is failing 'open', I suppose. Most likely the drivers' side one (which gets the most use?), but it could be any. Replace that ******! (Ask for details at the Saturn Parts counter.)

sounds like you have a faulty relay switch, relay's are contact breakers that open and close when power to them is asked for, ( like small timer switches ),your symptoms sound like this type of fault......

Forgive me if I seem to be over simplifying, but have you have you tried rotating the knob to left of the steering wheel (below the a/c vent)? If you rotate it all the way clockwise, it 'clicks' and the dome lamp comes on. Rotate counterclockwise and the dome lamp goes off and you adjust the brightness of the interior lights.

Dome light short


... Sorry to hear about this.
Have you checked all the fuses; to see if they are good?

I would start with checking all the fuses, the dome light bulb and burnt wires. (burnt wires will smell) If you didn't smell plastic burning while hooking up the DVD player, then you're okay. But check anyway.

If you can't solve the problems, call the Toyota service department for help. They may be nice and give you some help.

Good Luck!

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)

99 neon dome light wire diagram


Hooked all wires up right??? Fuse is fine??? Somehow, I do not think this is the case. I wish I had a dollar for every time I have seen this happen....I would be a VERY rich man!

You do not need a dome lamp diagram. You need to replace Fuse #13 (10 Amp) in the Power Distribution Center in the engine compartment. This will make the power return to the PINK wire and get your dome lamps working.

The only way that the RED/WHITE wire is going to have power with the ignition switch off is if either the ignition switch is shorted to power or the RED/WHITE wire got hot enough to melt the insulation in the wire harness and short to another B+ wire. This wire is supposed to have power when the ignition switch is in the RUN and ACC positions. Make sure it is in the OFF position. If this wire still has power, then YES, you probably smoked the wiring harness. If this is the case, the dash should be removed so that full access to the wiring harness can be achieved, allowing a full inspection/repair of ALL of the damage (there are most likely several other wires in the harness that have also been damaged).

The door keeps saying it is open and i replaced the door sensers but its not that can you help


Hello melvin... When the light stays on it usually means a door is open or the switch on a door or liftgate/trunk is bad. If the door adjar button is seperate from the latch assembly I pull the switch from the body and jump it out. Go one by one and you will find the failed switch. If the switches check ok and the connector is jumped and the light is still on then there is an open in the wires for the door ajar switch
Here are more procedures for troubleshooting...

Possible causes are :
1. Door switches stuck in closed position. Remove the rubber cover and loosen the screw holding the door switch. Pull out switch and check if the light stays on....if light remains on, fault is not with switches.

2. Anti-theft system ECU shorted. One of the wire goes to the alarm control unit. Unplug the alarm unit, if equipped and test.

3. Shorted interior dome light. If dome light is not working in the door ajar mode, remove the dome light and unplug the connector. If indicator light does not go off, fault is not with dome light.

4. Shorted Red/White wire. This would be the most difficult to diagnose as the shorting can be anywhere between the door switches to the indicator light. If you had done any wiring repairs prior to this happening, backtrack to check if any part of the wire is exposed and grounding

Good luck...i hope this helps.

2001 Ford Escape, dome light will not go off when door shut, but door ajar light is dark?Could this be the door switch? are there different switches for the door ajar light and the dome light? How can I...


The door switch provides a ground to the dome light... so there is no danger to you if you want to attempt a removal of the switch. A rusted or shorted wire in the door switch (of any door) will keep the dome light on.

Just recently my 98 Toyota Corrolla has started blowing a fuse.


I would remove the dome light, and disconnect the wiring connector, and then put in another fuse. If it does not blow, I would think that the dome light switch is shorted to ground.
