Have been trying to tackle an issue with my R32 GTR's climate control unit for a while now, and finally got some time to try and work out what's wrong. Basically, when I push the 'mode' button, it doesn't change where air is blowing - nor when I push the windscreen button. The door mode actuator just doesn't seem to move at all. Here is what I have done and found so far, but i'm honestly stuck at this point:

  • I've pulled the mode actuator out and pulled the 'locking' gear off, and re-plugged the unit in - and when attempting to change modes the actuator arm still doesn't spin (however, it can now be spun by hand).
  • When carrying out the diagnosis built into the climate control unit, I get the '31, 32, 34, 35, 36' pattern displayed when in Step 3 - door mode position check. This indicates a connector issue, but the connector is definitely plugged into the actuator.
  • The voltage from the pins on the loom that plugs into the actuator doesn't appear to change when I change modes - I thought they would (for example, I thought it would read different when at 'feet' vs 'windscreen'. The voltage readings I got (going from left to right with the pins at the bottom) were: 0v, 0v, 0v, 0v, 4.7v, 4.7v, 0v, 4.7v, 4.7v, 0v.

Any help or assistance here would be much appreciated.

Mode door actuator failure is very common. Pain in the arse to swap out too.

Possibly a bit of a positive / update. I removed the motor, and manually applied power to it and it spun happily both ways. The contacts themselves all seem to respond when they should when the main trigger wheel contacts the metal inside as well. Regardless, I pulled the motor apart and cleaned all the metal contacts, re-greased them with electrical grease and greased the gears. So it actually looks like the mode door actuator is in good working order.

However I now have no idea where to start looking from an electrical perspective. I'm hoping the central, main climate control unit isn't the culprit - but I believe that will have to be my next check. Just I don't know what I should be expecting it to do.

    • I've got a 2011 J50 that I imported six years ago. The unmodified factory AV system date and time has always been correct ( Japanese timezone of course ) up until last month. About two weeks ago, at engine start, the system wished me a happy new year ( in Japanese of course ). I can't think of anything that would make the system think that the date had changed, unless the GPS component has failed/reset somehow ? I checked the GPS reception in the system settings, and it can still see the satellites. Has any other J50 owner had this happen ?  It's no biggie, just annoying that it tells me the wrong date anytime I start the engine. 😅
    • Love following your adventures on IG, hopefully if you're still around in Japan when we visit again wouldn't mind going for a few beers with you (that's if you're keen on hearing how I hate Nissans).
    • ok so if i wanted to go 18's i would go for 8's  in front 30+ or 32+ off set at front and the back 9 would be ok? what offset should i aim for.. then can i do some  hunting for wheel rim choices..    If i get this - will this fit all around: Size: 18 x 8.5 +37 - n what tyres size tyre should i get for front n back?  
    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
