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/

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

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! :anyone::/

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...

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?

    • Hey was wondering if you ended up installing the R33 GTR speed sensor - I found one too and wanted to confirm it's a direct swap into the R34 6 speed?
    • After 23 years of owning a Skyline, finally had the latch go.  Followed this guide,  works like a dream again. Great Guide 👍
    • Hi all,   I’ve got the biggest lot of problems with my R33 GTS-T   It was a freshly rebuilt 25th anniversary RB25DET (plastic cas, neo cams) probably 6 years ago now   The engine was running so well but I fkd up badly and trusted someone I’d known for 10 years that was well known around Plazmaman for his welding and fab work. I added a lovely photo of some of his previous work. Not sure why my car was worked on by whoever did this shit     I’m normally someone who would never open myself up to something like this, I still can’t believe I did it. Trusting him literally fkd it all up for me. Everything has been a struggle, like it’s almost been 6 years that’s how much I’ve just on and off been trying to work it all out.    All I wanted was a car that danced down low, like full boost from around 3~3500rpm to redline, don’t really care what power it puts down (if it ever does) but I just wanted it to be quick to get on it.    He recommended the turbo to get, I picked Hypergear but he told me to get the front 4” with a T4 and 0.68 rear housing.    I was expecting all these beautiful welds, tidy fab work and paid for it to be ready to go to a tuner when I got it back.    I got a car back that was an absolute mess, I actually couldn’t believe it was my car anymore. I don’t think you could even call what he did welds, they’re disgusting.    So I stripped everything he touched off it and with every bolt I loosened it just got worse and worse.    I covered it and literally built and finished another car in the meantime but now it’s getting to the point where I really want my Skyline back.   Its a struggle because I paid him to do all this shit because I didn’t know how to and now I’ve had to try and figure it all out omg    Please excuse the bird shit horrible welds, I’ve got my show pony car and am so beyond dealing with this car I don’t even really care at this point.    If someone told me about what he did to my car I wouldn’t have believed them but it happened to me. It was unbelievable. He went missing, my car went missing, it came back missing parts, the straight af chassis rails bore the scars of being dragged up a trailer backwards, even the sandwich plate was bent. Everything was leaking and open to whatever fell into it, rounded off/ missing bolts, power steering oil and coolant everywhere, no gaskets, parts stolen off it, even managed to damage the sump pan.   Promised me he’d finish the car, knew what it meant to me, I paid him thousands and thousands just for him to trash it. He told me he was fully licensed and insured, come to find out he’d cancelled his ABN, so obviously no insurance. I had laid up insurance on the car and would’ve been covered but I was scared they would’ve written it off or because the business was no longer trading I’d still be liable.    He was supposed to:  New fully custom mild steam pipe exhaust manifold with turbo location moved from factory position to high forward mount. (I don’t know if it is a mild steam pipe, I’ve got a funny feeling the waste gate isn’t in a very good position and I don’t think the outlets off each cylinder are equal) 4” custom stainless steel dump with external gate (he re-plumbed it) Cut and shut OEM intake manifold with throttle reposition (I ended up doing the throttle reposition) Box in pod filter (left out) New 100cel catalytic converter (pretty sure it’s there but unsure if it’s 100cel) Front mount intercooler piping fabricated to suit (all smashed up and rusty holes where he was supposed to make it look standard where fmic piping passes through. I don’t even think my front bar is going to fit 🙄) Custom 5” intake pipe from pod to turbo (didn’t come with it so had to do something to make it work with the Z32 afm)   Engine: Full cylinder head service & machining  Brand new valves Precision upgraded spring kit Engine block honed New bearings  New piston rings  New ARP conrod bolt kit New ARP head studs Cometic head gasket VRS kit   ATR43SS2 ball bearing turbo 0.68 rear housing  Turbosmart 45mm external wastegate (got delivered to the fab bloke, I’ve got no idea what spring is in it, I’m assuming the one that came pre installed) Walbro 260 fuel pump  Nismo 740cc injectors (tested to 880) Spitfire coil packs GCG FMIC RB25DET manual 5 speed 4:11 rear diff   I’ve got an Apexi Power FC in it atm, I was hoping to just get it to operating temp to make sure everything was okay before towing to a tuner but it’s over-fuelling too much. I don’t think that’s going to happen so i think I’m going to get either a Link G4 or Haltech for it. What do you guys recommend? I can’t work out the power FC so just gonna give up on that one     It’s got an exhaust leak coming from somewhere I can’t see 🙄    The fuel pressure was steady but now it like drops from 40 to 20psi randomly (noticed this yesterday)    I’ll attach pics of the shit he put on my car and the engine bay now as it sits    I really just need some help, I need a tuner in Sydney I can trust, I’d like to be with the car while it’s being tuned if possible, I know it looks terrible but unfortunately I’ve just got to put up with it for now and fix the cosmetic stuff later   Do you guys think the manifolds are going to be okay? Or do I throw the exhaust manifold and try again?   I don’t even think these combinations are going to work tbh   I know everything I fitted was rated to be able to take at least 400kW but most rated higher    If you’ve gotten this far I really really appreciate it 🙏 I don’t mind if you trash me or the car, I made a rookie error and f**k I’ve paid for it. As you’ll see 🙄  
    • From everything I’ve heard you’ll be waiting a long time for  the parts to arrive 
    • Have you looked at the workshop manual?
