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.
