hi to all. my omega 2.6cdx 2003 has just begun acting wierd!
car drives fine,no warning lights,all seems fine except :
noticed yesterday that "lights on " warning buzzer was sounding albeit much quieter with key in but stops when ignition on or with key removed.also sounding with no key in if i put parking lights on ( again quieter thou)
today after further investigation found out that the interior light is staying on once you open the door or operate it from the light switch and wont go out unless you turn ignition on.
all is fine with engine running,map lights work ok and interior light will turn on and off with light switch if needed.
interior light still wont go off if warning buzzer is unplugged
warning buzzer still sounds quieter if interior light is unplugged.
warning buzzer works as normal if key is left in and door is opened and also if you leave lights on and open door.as it should.
car will lock and unlock with fob as normal but no red light on facia ( side of radio) and no deadlocking happenning.
all door lights are working normally and each door switch has been removed and checked .all double contact type with circuit to earth when released and clear to earth and each other when pressed.
removed fuse 12 marked as courtesy light and the other marked as courtesy light 23 i think ( as in manual)but courtesy light stays on even with fuses out.
has anyone any other likely suspects ?
 thankyou

Moisture in the light switch...

just removed the light switch . plugged interior light back in . comes on when you open the door .stays on !
buzzer still sounding quietly !

[cam.in.head]

is the delay function in the interior light or elsewhere ?
still no deadlocking either !

[Doctor Gollum]

OK, it won't lock if one of the front doors is open... this is done via the contact switch iirc... which might also have a bearing on the interior lights/buzzer.

Did the buzzer stop with the light switch removed?

Had very similar on my daily car, the drivers door switch had water ingress, dried it off and all ok. A quick temp fix is to swap the passenger door switch over while you are drying off the drivers switch.

hi .drivers door switch nice and dry and tests electrically fine. even if the switch is unplugged buzzer still sounding !

I had very similar, albeit not on an Omega, but a VW Golf Mk4. Traced the cause to the actual ignition lock / barrel. When the ignition key was turned to the 'off'  position, enough to release the key for removal, the final 'click' from the barrel as the key was taken from the lock couldn't be heard.
A squirt or two of switch cleaner followed by the minutest squirt of lube similar to WD40 did the trick.
Hard to explain clearly, but the last 'click' you normally hear when phyiscally removing the key out of the barrel couldn't be heard, as if it was sensing the key was still in the barrel. After the bit of a clean and the minimal of lubrication, all was back to normal.

Good info here 
I've had the same issue with many vauxhall ignition barrels and now use a 3in1 type spray oil via a straw to lightly lube the mechanism
when sticking it can leave the radio or other electrical systems on etc

will check the ignition barell is working correctly tommorow. many thanks for all your help so far

[johnnydog]

I must stress that any lubrication must be very very minimal and certainly must not 'flood' the barrel or tumblers. On the Golf, I recollect there was a small hole in the surround of the barrel visible above the key aperture - big enough for the straw of the WD40 to access, but do not over lubricate it as it may cause problems with the tumblers.

If lock requires recon.

hi.
front door switches removed and checked again. swapped side to side .no change.
one thing that did pop into my mind thou.when i first noticed the buzzer noise( friday after work) i got out of the car and locked it .interior light had gone out .
the interior light now staying on seems to have happenned after yesterday morning when i removed each door switch to check them. i didnt disconnect the battery to do this as i didnt think it  at the time but once i remove any of the switches from the door im effectively removing the earth at that point and joining the two wires together! .could this have caused the interior light problem or alarm / deadlock issue ? .
deadlock always worked up to this point as far as i know .

ignition barrel all seems to be working fine. key turns nicely ,all operates as it used to and when you remove the key the barrel jumps forward with a nice click turning off the radio

Gixer had the same issue, cant remember the cause.  I think it might have been the light switch.  Lemme contact him, see if he remembers.
