hey im just looking for some information and if anyone can help me,

my drivers door didn't lock unlock so I replaced the lock mechanism it worked, perfect!!

rear door didn't work bought a new locking mechanism everything works bar lock/unlock. on this side the window everything works,

I have tried the mechanism in the other passenger door it works so that rules out the mechanism and puts it down to the wire loom? if I'm correct.

when I put a multimeter on the door wires etc sometimes it can fluctuate then stays at 12.3ish I will push the lock/unlock button and it'll drop to 10v and then go back up and stay at 12vish, is this correct?

its frustrating me as its all looks okay and works? I've checked the loom and i cannot see anything out of the ordinary inside the door or the black bit in the door crack,

I'm not sure if i have posted this in the right place im sorry if not!

so after some careful reading i went and looked in my door pillar thing to realise some wires were snapped put back together works fine now!!!!

always check ur wires in the door!

now left is to get this random unlock and locking to stop
