Nissan Primera P12 xenon headlamp aiming /cleaning

I think the cold climate is about more fluid and/or higher pressure with each spray. Notice the tank has almost double volume too.

Searching ebay for 28920AU31A returns identical results to 28920AU310. Seems I have to go to Nissan with this one.

Thank you for the detailed description, Electrolyte

Living in Norway the headlamp washer is an important part. I didn't know that until the night I drove across a mountain in bad weather and it wasn't working. I lost vision frequently and had to stop at every gas station along the way to clean the lights.

Nissan parts catalog gives two part numbers

From the drawing I'd assume part #4 is the one I'm looking for (as it is not included in the drawing without lamp cleaner). Searching for that partnumber on ebay returns results that looks more like #8 than #4. You seems to also confirm that ebay search results are wrong.

Seems like I have to go to the Nissan reseller (as this is Norway £50 would be extremely cheap), or find a donor car.

Thanks for your description, Electrolyte.
I'm trying to find the replacement part for the cleaner motor. The parts catalog doesn't say which of the motors that goes to the lights. Does this look like the right part?

A test in the dark revealed that the aiming problem is solved. I also opened the electronics cover on the actuator while I had it out. The copper had turned green at some places. I cleaned it and gave it a round of contact spray. But I'm sure the electronics was not causing the trouble this time.

I think the ball in clamp concept seems very weak. From what I've seen today I'd expect it to fail easily if there is force applied to push a light bulb in. From now on I will take the actuator out whenever I'm doing any work with or near the light bulbs. I don't know how my ball popped out, cause I've never done any work touching the RH head lamp unit. It's the LH unit I've worked on.

Also the headlight cleaner will not work unless the headlights are turned on. 

@Electrolyte
Where was the head lamp cleaner motor located? How did you access it? It seems to be one in front of the tank and one at the rear. The front one seems to require bumper to come off, while the rear seems easier accessible.

I feel embarrassed for even asking how to get the aiming actuator out. It was very easy. For those how may google this thread, here is the howto:
- Disconnect the cable under the aiming adjustment pot
- Take off the rubber covering the high beam bulb
- Turn the aiming mechanism 45 degrees so that the area where the cable was connected goes towards the high beam.
- Pull the aiming mechanism out, bottom first.
That was the way I did it. Keep in mind that my low beam was very low and did not respond to the adjustment pot. I think, if your aiming control responds to the adjustment pot, you should adjust it all the way down before you start.

When installing, make sure the rod with the ball is extended as far as it goes. Then insert mechanism top first.

At the front of the aiming mechanism is a blue ball at the end of a rod. This ball should fit into a clamp inside the headlamp unit. I think (hope) my problem was that the ball had jumped out of the clamp. The clamp is open at the bottom. That's why you want the rod with the ball to be as long as possible when you angle the aiming mechanism to put it in / take it out.

I hope this fixed my aiming problem. I'll need a dark place to see how it is now.
