Update: My original lock actuator has decided to work now, so I've refitted it. I don't expect it to last forever, but I also don't fancy chucking £60 at a door lock actuator and/or £35 at a GM5 repair if it's deciding to work now :lol: I found the lock actuator a quick and easy job so I don't mind if I have to remove it again in a few months' time. Hey ho!
