Nissan R32 GTR - Climate Control Mode Door Issue

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.

      @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣

      I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia.

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
