Thanks for the reply - the windows work with the switches as normal, the global closing works from the boot lock, but not the driver's door lock (passenger lock knackered since I've had it) I did look at the tailgate gaiter wiring - when I looked in there it looked like a small bomb had gone off! - a black and blue thickish wire (2.5mm crimp worked) had broken, brown/red, yellow/black, and red/yellow wires all had broken insulation and bare wires exposed, in addition to which both hi-level brake light wires had broken All crimped/insulation taped as required, but perhaps I should have a look and see if I missed any others: (I knew the hi-level brake lights weren't working and pleased that I've fixed them now but don't know if I've inadvertently fixed anything else!) I will look again at the driver door wiring and other doors, but any idea of the coloured wires I should focus on for the locking and is there an easy way of detecting broken wires within an unbroken insulation? Avometer, I suppose?
