R33 GTR door lock cylinder only unlocks?

I finally mustered the willpower to take apart the door on the driver side to figure out why it was rattling in there and also why my door locks can only be unlocked with the key but not locked from the outside. Now with the door card removed and the actuator arm unhooked from the door lock barrel I see that if I turn the lever it acts on the lock and unlock function works in both directions.

 Any advice for figuring out why my door locks are unhappy to lock but are seemingly fine with unlocking?

The rattle suggests you need to follow all the links. It's a complicated mess between the inner handle, the solenoid and the key barrel. There are little plastic clips that hold various of these together at numerous points. Loss of one can make it impossible for one rod to properly move the other.

I figured it out. It was actually comical. After pulling out the cylinder I realized it turns both ways. When I put it back in suddenly it was fouling on something. Looked carefully and realized the lock cylinder arm was facing the wrong direction. Checked the cylinder on the driver side and realized it has an L on the arm. Pulled off the passenger side door card and removed the lock cylinder and put the “driver side” lock cylinder into the passenger side door. Now it works in both directions. 
 

So anyone with a similar issue where the key can only unlock the door but you have to lock it from the inside should check first that their lock cylinders weren’t mistakenly swapped at some point. If the lock cylinder arm is facing the front of the car instead of towards the trunk this is the warning sign.

Hehe. Thread left turn as usual.

What was rattling?

Loose bolt that adjusts the unlock/lock rods. After futzing with the adjustments to try and get it to the “right position” it shouldn’t rattle anymore. Like any project with this car that I expect to only take a day though this has immediately turned into a week or longer because the factory vapor barrier is ripped up and some clips are missing so I want to fix all of that and get it absolutely perfect before putting it back together. Of course between mail ordering parts and the right sealant for the vapor barrier only being sold by mail it’s going to be a solid 5 days before any of that appears.

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      He's right ~ there is no 'magic' with stuff like this ... it is more likely that in the process of looking for the short, the loom/wire 'incidentally' got moved in the process, thus removing the short ~ now, that maybe a wire (in a loom) rubbing against the edge of some grounded metal, that's worn through the insulation, causing the (now intermittent) short to ground. If one wire in a loom has been damaged in this fashion, it's reasonable to presume that other wires beside it may have also be damaged, and now exposed...you can bet the green crusty copper corrosion will start... ...that'd be a pisser, Murphy's Law steps right in as GTS observes...but worse, something like that is easier to find when shorted...ie; unplug bulb and fuse, and put multimeter in continuity mode so you get constant beep, and carefully poke about hoping to find if some movemet of the harness stop the beeping.... ...it's still all a bit Arnie tho' ..It'll be back... 😃

      Yeah, but knowledge of one wire's insulation worn through to short on earth implies the possibility of other wires doing the same. I had my power steering die, because the wire that runs to the solenoid valve on the rack runs in the same loom as the power wire for the O2 sensor. And when the O2 sensor/wire did something stupid and burnt part of that loom to death, the only indication was the shit(ter) fuel economy and the heavy steering. It took deep excavation of the looms in the bay to find the problem. Not wear through in that case, but similar shit.

      Mistakes were made, my R34 Story

      Ah, I thought he'd wired it to one of the spare ECU inputs! Too long ago since I read that post, ha ha. I've been arguing with radiators, harmonic balancers, alternators and rust since reading it.

      Correct. The ECU cannot read oil temp. (Well, I think it probably can in some situations. I did have the thought of potentially repinning the ECU when I was doing oil pressure). I am using this into the MPVI dongle, so that the MPVI dongle can read oil temperature. It is attached to a VDO gauge which is obviously calibrated to whatever curve the sender actually is using. This would be easy if I could setup a table of voltage to temperature like many sensors, but it appears I cannot do this and can only setup the transform rule which appears to be Input (voltage) x Multiplier, and add an offset. This to me means it MUST be linear. So it may be a complete waste of time wiring this into the ECU. The idea was that the MPVI3 has standalone logging. I wanted to use this instead of a laptop with serial cable (for wideband) for long datalogs. Given the wideband also has electric interference, I may never trust this either in a world where the serial wideband and the analog output wideband do not agree. Last time I did a trace I could see the two wideband traces follow each other, but one was a little leaner than the other. I plan on playing with voltage offsets and actually driving the thing to see how close they correlate. If they never correlate... then, well, maybe I'll never use either. Ideally I'd like to have the Analog wideband read ever so slightly leaner than the serial one, because the serial one is 'correct'. Tuning the car to be ever so slightly too-rich would be the aim. Not needing to have a laptop flying around in the footwell connected with cables is... an advantage. About the only one from the forced upgrade to MPVI3.
