I have some problem with my winter cars interior lights. They don't light up at all.

The door contacts work, the buzzer goes on when driver doors open if headlights or key is still in ignition.

I have checked the headlight switch and it works and when checking with Ohm-meter it is closed when interior lights are on ( pulling the knob)

Fuses are good, light bulbs are good.

Where should I look further?

Since all lamps are out, even the ones in the vanity mirrors, map lights, door lights, every damn lamp that should be on when a door is open don't work it must be some major feed problem.

Everything else in the way of lights are working.


Thanks

More than one fuse

[Jan Suhr]

Yes I have checked the ones that are mentioned in the manual. If I remember correctly it was number 12 and 15. And those fuses are connected to other things that do work

[Doctor Gollum]

Do they come on when you unlock the car?

[Jan Suhr]

No, they are dead in all possible ways.

[Doctor Gollum]

Have you changed the radio and did they work before?

[Jan Suhr]

Yes the radio is changed and it was when I got it. I have changed to another one. I do have the original radio, a NCDC2013, I can hook it up and see if it will do any difference.

[Jan Suhr]

I tested with the NCDC 2013 connected but lights still out.

Have you checked fuse #7?

On my Omega fuse #7 is for the power windows. Earlier models had #7 for the interior lights

According to my manual it should be #12 and #15 and they are both good and other things that are on those circuits work.

I have also noticed that the daytime running lights don't work, the Scandinavian models have that and a special relay for that. But tha tis a whole different circuit and shouldn't be connected to interior lights.

When door is opened those light should (if everything OK) lit. Then after a while those lights go off. What "Brain" put them off? If then when door still open the head light button is pulled should those interior lights come on again? I cannot test as my Omega does not have battery now.

[Jan Suhr]

It's controlled by the Central Lock Unit/Alarm. 12 volt is feeding the lights from that unit. In my case I suspect that the feed is broken out from the unit.

I got them working now, it was the K154 relay that didn't work.

Since the rear cigarette lighter socket also didn't work I started to think if it could be related and a search here on the forum pointed out the K154 relay. It's not easy to reach under the dash.
