Ford Wiring/Electrical :: No Dome Light And Door Ajar Always On
Nov 20, 2012
My dome light does not work and door ajar light is always on. I cant even turn the light with the switch on the side. Just don't know where to start. Do you think it is a switch on one of the doors? I have tried spraying cleaner and WD40 in there but it has not worked. Its been this way since I bought the truck but it is starting to drive me crazy....

I have a 99 f450 and my door ajar light is on. Where is there a door sensor for that so I can turn it off.

I just purchased a 2006 E-350 15 passenger van. ~85000 miles. As soon as any door (except the very back door) opens, the dome light comes on, as expected. However, when you close the door, the light doesn't go off. There are two ways I've found to make the light go off:
1. Reach a speed of 10mph
2. Wait several minutes (i haven't timed it yet, maybe 10 min?) without opening a door
I've read that the keyless entry remote can control this, but this van isn't equipped with keyless entry. There must be some factory setting that can be adjusted. Also, any thoughts on adding an aux jack to the stock AM/FM/CD stereo? Maybe I should bite the bullet and install an after-market deck?

I'm having a problem with my interior dome light and my door chime bell not working in my '01 F-250. I found that the bulb was blown,so I replaced it thinking it might fix the door chime bell also, thinking they were wired together from the factory.
The new bulb didn't fix the problem. I recall that when I noticed the door bell didn't ding-ding anymore was about the time(when it got dark), that I noticed the dome light was out also.
What I may check? The fuses all work, the interior dome relay switch works and I see nothing else in the owners manual to look for as far as dome lighting and door bell chime.

Two Issues....
1.My rear dome lights work when manually turned on. They do not come on when the door is opened. However, the front dome lights do.
2.The lights on my side mirrors turn blink when using the turn signal, and when hitting the lock/unlock/remote start buttons. They do not work when driving around with my head lights on.

we just bought a 2002 Excursion and it has a few issues. First off the door, the ajar light will not go out, however, the dome lights are not on constant, they come on briefly while the key is removed and do work with the roller switch. Also the radio doesn't shut off with the key removed until the timer relay kills all power. I have ohmed the door switches to ground all the way back to the VSM/GEM module. The door lock/unlock switches do nothing for any of the doors, the actuators don't even try to move. The auto headlights also do not function.

A friend has 2001 Explorer, whose dome light isn't working from the driver's door. Did a quick Google and found a number of excellent answers and how-tos on this site, all focusing on the door switch. Problem: the door ajar light works properly, presumably clearing the switch.
My understanding is that the dome light is triggered by the GEM via a relay. When I considering the following:
- The dome light turns on via the headlight switch;
- The dome light turns on by opening the passenger door;
- The dome light does not turn on by opening the driver's door; and
- The driver's side door ajar functionality works -
I am led to conclude that the fault would lie in the GEM module. If the GEM is indeed bad, then the light will probably just stay out. But is there something else that I might be missing?

I had a problem with my door ajar light always being on, I was able to find out that it was in the sensor for the back glass and was able to fix it. But now when I cut the explorer off and remove the keys the dome light comes on instantly even if no doors are opened and the lock/unlock button on the driver door won't work. However if I manually turn off the dome light my lock/unlock button starts working properly. Also if I do not manually turn the light of with the roll switch the light will stay on until the computer kills the power to it about 10 mins later. What could cause this??

Bought a '02 V10 gas 4wd Ex a week ago pretty cheap, and looking to fix a multitude of little issues.
I have been reading about the door ajar warning light issue, and mine alike has door ajar light always on. However, my dome/interior lights do not react to the opening of any doors/rear door hatch.
It's not out of the question that the last owner might have disconnected what he needed to to avoid fixing the problem and still use the truck. Where to start given I can't troubleshoot down to one particular door ajar sensor?

My Dome lights don't work when you open the door. I can manually turn them on though. Also door ajar light is on. Are these issues caused by the door latch switch? Also have no fog lights I replaced the switch and bulbs. I have a 2003 F250.....

I can't find out why my dome light doesn't work. I threw a bulb at it first, and then a tester but found no voltage with the door open or the dome lights dimmer roller clicked over to "interior lights on". I do get a door chime with the door open, so seemingly the door switch is working. Fuses 4 and 14 are good. They seem to be the related fuses.
Here's what I've checked.
1.. Fuses are all good.
2.. Removed and tested the relay. It tested properly, closing the large contacts when voltage is applied across the two coil terminals.
3.. 12V is present at the large left contact in the relay plug.
4.. I applied voltage to the relay output pin (the large contact next to ^^) in the fuse panel and get the dome/cargo lights to illuminate, so I know the wiring from the relay to the lights is good.
5.. The two smaller relay pins upper and lower look to be the relay coil/turn on contacts. (The middle contact is not used) There is 12v on one of them and it seems the other should be grounded with a door open or when the dash roller is rolled past the detent. I'm not getting this grounding signal.
6.. I do get a warning chime if I open the door while headlights are on etc, so it looks like the door switches are working.
Just got back in from some more testing... Here's a breakdown of how the relay works:
- Relay socket we're looking at is the upper socket.
- High amp 12V power is on the left large vertical contact. The relay's function is to port this voltage to the middle large vertical contact. (the load contact)
- The middle vertical contact (load contact) goes to the dome light and cargo lights.
- The upper horizontal contact is one end of the relay throw coil. This one has 12V present when probed.
- The middle horizontal contact is not used. (actually it's an empty socket with no female terminal behind it.)
- The lower horizontal contact needs ground applied to it to get the throw coil to close the high amp contacts.
With the relay plugged in, I was able to sneak a thin probe to the lower horizontal contact and ground it. The relay activated and the lights came on. So, for some reason I'm not getting the grounding signal to the relay with the dome light rocker or the doors open even though I get the door chime.
Apparently there is something between the door switches and the dome light/roller switch and the relay? Is this the GEM module? If so, I don't see the reason for anything between the switches and the relay? It should be a pretty basic relay circuit?
Is this something (GEM?) programmable, or testable? I don't want to throw parts at it. Looking for a wiring diagram, a diagnostic flow chart or a pin out?

My Viper 2 way alarm, instead of the brain being wired to each of the 4 doors individually. The installer ran 1 wire to the dome light. Seems to work fine as far as arming/disarming/locking/unlocking, but since the dome light stays on for 10 seconds or whatever after the door is shut, when i arm it.
The 2 way remote says "door open" because the light is still on so it thinks a door is open. this eventually times out and all the sensors arm, but there's a long delay. it arms fine and no alerts pop up if i lock the doors first from the outside keypad on the door, making the lights go off, then hit arm on the viper, and everything is good to go.
Can I change it so no matter what, as SOON as i shut the door, the light goes off? I want there to be NO delay, if possible. If not, I may need to just have the installer run a wire to each door and take the single run to the dome light off, as it is sorta annoying to me.

The dome light and door ajar light on my 97 Ranger stay on. The switches are good, is there a relay or other device in the circuit?

Have a 06 and the dome lights stay on all the time. I had to pull the bulbs out of all of them. They would come on during the night and run my battery dead. The lights just come on while driving down the road and won't go off either. I can hear a clicking in the dash while driving where they are coming on and off from a really or something. Sounds to me like it's coming from the instrument cluster.

I was replacing the dome light in my 06 Ford F350. I tested the light and it worked then while screwing it back in, the lights when out and then the radio. I suspect it may be a fuse, but have yet to find the culprit.

Vehicle: 2002 f250 xlt 7.3 powerstroke reg. Cab
Issue: door ajar light stays on, power locks on driver and passenger door don't work, radio stays on after truck is off an door is opened.
Events leading up to issue: went to temporarily hook up a wolo dixie horn to see if it worked. Wanted to do it fast so I took + cable, tied one end to the battery terminal and then connected other end to dixie horn relay. I then grounded both negative wires to the truck. One ground on the frame the other I temporarily wrapped around a one of factory ground mounts under the dash. Immediately after doing this the problems stated above started.
How can I fix this. I need to fix this by tomorrow. I have a guy from Craigslist coming to look at the truck. Now the 4x4 issue.
Truck has zf6 manual and the electric 4wd select ****. Just thought I'd list this if it was needed to be known for solutions.
4x4 high light stays on in while 2wd all the time. 4 low will stay on after switching back to 4 high and 2wd but it goes out if I ether stop the truck shut it off then restart it. or back up and slam on the brakes. Also when in 4 high the front driveshaft won't spin. However It will spin when in 4 low.
Another random issue I'd thought I'd just list while I'm writing this.... Cruise control does not work. And when I press the "on" button and the "coast" button at the same time the horn honks.
