V28VX37 Posted October 17, 2015 Share Posted October 17, 2015 (edited) Hi all, My R34 GTT passenger door lock has started playing up and won't lock sometimes so I need to check it every time when parking, annoying. I just pulled the door panel off and had a lock at the mechanism, see photos below. The rod system seems fine and I WD40'd everything whilst there but it didn't really help. What I noticed is that the door locks when the actuator rod is disconnected, so the theory is that the actuator has become too weak over time to move the whole system. Any other suggestions before I go and buy a new actuator? It's a sedan too so finding one is going to be fun... What's involved in changing the actuator? I'm not quite sure how to disconnect the door handle rod, and also couldn't see any actuator wiring/plug anywhere, though it could be somewhere inside the door skin. Cheers Edit: This was a good reference on how to get the door panel off: http://www.sau.com.au/forums/topic/285604-tutorial-r34-gtt-door-panel-removal-guide/ Edited October 17, 2015 by V28VX37 1 Link to comment https://www.sau.com.au/forums/topic/460412-how-to-replace-r34-gtt-door-lock-actuator-door-not-locking/ Share on other sites More sharing options...

Does anyone know if the coupe and sedan actuators are interchangeable?

DINHosaur Posted October 21, 2015 Share Posted October 21, 2015 Hey man I've got the same problem, passenger side aswell haha (R34 25GT Series 1 sedan) Started playing up a couple weeks ago Wouldn't be so bad if the problem was unlocking but that seems fine, just locking is the problem Not much info googling this problem... wonder if we can just buy an actuator from a Nissan dealership?

Looking forward to any suggestions! That sucks, sounds very similar to my issue. I haven't made much progress but have found some actuators at http://www.brisbanemotorimports.com.au/nissan/vehicle-electrics/door-lock-actuator/ Looks like they have all other actuators in stock except for the front passenger, grr. I am pretty sure you could get one from Nissan for like >$200...

V28VX37 Posted November 29, 2016 Author Share Posted November 29, 2016 I replaced the actuator (DIY: https://www.sau.com.au/forums/topic/465953-replacing-door-lock-actuator-in-r34-gtt/ ) and it worked well ... for a while. It's started to play up again, same symptoms as before, always unlocks but sometimes doesn't lock. I'm wondering if it's something else that might be jamming it? I'm thinking of attacking the mechanism with WD40, any ideas where to focus on?
