Hi it was suggested my drivers door switch had failed, it is a double switch ie two wires to it and one ground via the screw.

On testing between the wires it has continuity until button is pressed, between a wire and the ground it has continuity until button pressed, again on the second wire to ground.

So is this correct? I though because of this it had failed and purchased another second hand one off a kind member on here, that tested the same but solved part of the problem, the dead lock now works on locking and the courtesy light goes off, but on opening the drivers door the others all lock.

Better than it was but i have to now assume the door switch is ok?

   anyone?

Strange imo,that both switches behave the same on a meter (if Im reading it corrrectly),but the replacement has solved part of the problem.
Im more useless with electrics than I am with most other things,so cant offer any technical insight unfortunately.
Im sure someone on here will have some useful info though,they usually do.

...door switch had failed, it is a double switch ie two wires to it and one ground via the screw.

I am thinking back to my Mk.1 Astra and Nova days here (never needed to pay any attention to door pins on more recent vehicles) but I thought the wire(s) going to the switch carried the negative current from the interior light which then earthed out on the chassis as the door pin was operated?

As Jamie recently corrected me  ...... it appears to be a bit  more complicated than that. The wires to the doors pin switches are IIRC grey & grey/white, 'earths' on a Vauxhall are brown.

Direct earths are brown, not switched earths...
