v70 locking issues

[valentino]

One rear door lock plus boot wont lock,all fuses ok,any help guys？

try resetting the system...

Ignition to position II and hold the front window switches, in the drivers switchpack, in the up position for 8 - 10 seconds then ignition off, lock and unlock via the fob twice.
this should reset the locks and can cure a few problems.
welcome aboard.

Just tried that my friend,no joy！

That would probably mean the solenoid in the lock needs either stripping down and cleaning or just swapping for a new one.
Sorry to say.

An §§§§ load of wd40？

What happens when you have the driver's door open and you push the magic "lock" button - does everything lock then unlock or does it do nothing (try with the key at position I as well) - join the central locking party =(

Just tried lockin and unlockin wit drivers door open,nothin happens,tried the window switch technique wit key in position 1 also,no joy again！

Sounds like an electrical issue. Sadly I am still hunting for the right relay to do the job. If you get there before me; let me know will you =)

I believe it to be a lock solenoid that needs replacing (the one that physically unlocks/locks the door. I've read about it on VOC, if the reset doesn't work then it's the solenoid. Quite common in the earlyier P2 cars.
Sam, since we changed the n/s doors, I would suspect either the rear o/s door or the driver's front switchpack.
We'll have to hook up some time and I'll have a look at that switch pack (mine went furry at the connections and played - up something silly). After that, I'd really start looking at the solenoids. I have a spare tailgate with a working lock, we could wire that up and see what happens?
