F24 is apparently the central locking, alarm and horn according to my manual.
I thought I could resolve this problem long term by just living without the central locking, but would be annoying not to have a horn...
Looks like earthing the connection in the GEM or taking the door panel off are the only solutions :unsure:
but would be annoying not to have a horn.
More I think about this, I think it might be connected to water getting inside the doors and causing the intermittent fault with locking and the door ajar light.
Well taken fuse out for central locking, and still have a working horn - so a temporary solution for now. On the case with an auto electrician for a bypass solution, and will let you know how I get on...
Auto electrician has sorted this for me today. Passenger door now bypassed so that door not shut light no longer on, and central locking now functioning again.
Door not shut light still works on remaining 3 doors.
He had to take the door panel off to do it.
New door actuator would be £300 - so prohibitive on a car of this age!
