Hi guys,
I have a 2000 Omega 2.2cdxi estate.... today the audible warning for "key left in ignition" and "lights left on" seems to have stopped working. Everything else seems to be ok other than no backlight in the headlight, front and rear foglight switch cluster.
Can anybody enlighten me as to the possible reason, location of the likely culprit and solution.
thanks

Hi again, I know my question probably sounds a petty issue in comparison to the other more obviously serious problems on this forum but I have just done what I feared i would :-[,
I have got so used to the warning buzzer telling me in daylight that I have left my lights on, that when I went to the supermarket this morning to do the weekly shop (in heavy rain hence the headlights) I parked up, locked the doors, did the shopping and returned nearly an hour later to a very flat battery !! :'( with just enough power to operate the central locking :y ................ I now know from personal experience HID headlights can kill a battery in a very short time!!! now apart from feeling very stupid, and at the same time very lucky that the central locking worked, I then had to rely on the good nature of my fellow shoppers to jump the car.
So any suggestions would be greatly appreciated ........ does anyone know where the buzzer is located ...... probably somewhere completely inaccessible ????
thanks

If the backlight on the switch failed at the same time as the buzzer stopped I would expect that either the switch is faulty or a fuse has blown.
Fuses are easiest to check so I would start by trying to find a faulty fuse.
The switch is more trouble to fault find & it could be either the light switch or the ignition switch.
Hopefully someone will post an answer who has actually had this problem.
Do your puddle lights in the doors com on when the door is opened?

Post `98 models have the audible warning incorporated in the main light switch
-
so suggesting an internal fault in the light switch if not illuminating either ???.... obviously has power going to it because all lights including fogs work.

Puddle lights not working either ................. now thinking fuse .... but which one ???

Not all ;) ;) ;) ;) My 99 MFL has the buzzer under/behind the glove box. :y :y

Seems confusion reigns regarding the answer ;D ;D :D

Update :
:y thanks to everyone who responded..... checked all the fuses this morning when it stopped raining taking each one out one by one ........... none blown
switched on the lights and bingo "lights on" warning buzzer working again ..... so is the "key in ignition" buzzer as is the door puddle lights ............. so must have been a loose fuse ..... now just need to isolate which one so if it happens again i know exactly where to look. that job can wait for another day as it is starting to rain again.
PS For Rob/Andy - just for info, now I can hear it the buzzer on mine is definately located behind the glovebox !
Thanks again to everyone.

Thanks again to everyone.
The flat blade fuses are made of something quite brittle (aluminium maybe?). It is quite common for them to fracture and then make intermittent contact. Reinserting the fuse out is often enough to (temporarily) establish contact.

thanks Andy
will keep an eye on it and if it goes again will find the culprit and replace.
thanks again for the guidance

The wiring diagram in Haynes appears to show all sorts of interior electrics (including heated seats) fed from fuse F20.
Seems a bit odd to me to have instrument lighting on the same fuse as heating elements so I don't really trust the information :-\
-
I agree, I found a fusebox layout on-line which also suggested F20 but the other things supposedly running from that fuse where all working ............. thats the funny thing everything appeared to be working other than the buzzers, the light switch backlight and the door puddle lights ??? Will update when I find out which one

Now Confused ........
Just gone out to car and buzzer not working again, checked all fuses again, still not working,,,,, however it now looks like it's something else ! ? ..... passenger door puddle light is working, headlight switch backlight is working, drivers door window switch console backlight is working, interior courtesy light working when driver door open,,,,,, the only thing that is not working is the driver door puddle light and buzzer for both lights and ignition key, then whilst I was standing puzzling over the problem the drivers door puddle light came on on its own ( I touched nothing !) ,,,, with the door puddle light on the lights and ignition key buzzer both worked, shut the door, opened it again, and no light again and no buzzers again.
So by a process of elimination the problem must be linked to the light in the drivers door :
option 1 : broken filament in bulb making intermittent connection (surely its not wired in such a way that a blown bulb would create an open circuit and stop the buzzer working?) replacing bulb tomorrow to check.
option 2 : system not recognising the door is open so no light and obviously no buzzer because its designed to warn you when the door is open ...... this is my favourite at the moment but am being thrown a curved ball by the interior overhead courtesy light coming on with the door open, so that is recognising the open door ..... so now thinking is the puddle light and buzzer on a different circuit to the interior courtesy light and is there a possible broken wire in the door loom ??
anyone got a circuit diagram ????
-
The door switches have two independent contacts. It is possible that one contact is still functioning correctly while the other has become intermittent.

Now feel slightly embarrassed and a bit of a numpty !!! Turns out to be the door switch after all .... didn't even give that a thought based on the fact the overhead interior courtesy light was coming on when the door was opened.
Thanks for the pointer Andy
