Hello everyone!
Please pardon for creating a double thread! (I have already asked this in the Suspension area, but I guess I would get more input in the main formum)
I'm trying to remove the headlight auto leveling sensor from the rear.
But I cannot seem to reach for the connector.
On the sewell-lexus page I found a following scheme:

I think I can reach for the area circled in red but the connector is further to the rear of the car.
Has anyone ever removed theirs and can help me out on how to do this?
Thank you very much in advance!

We followed the wire to the trunk and disconnected it there.
Here is the picture of the sensor taken out, the clear part has been in the trunk (well naturally

Here is a close-up shot of the other side of the sensor.

It's strange that the connector only had three wires but the wire near the sensor has four, the one that was missing (white) on the other side is torn apart.
Well the part circled in red with arrows needs to rotate pretty freely. I have tried to rotate the sensor in the front when the little ball joint thing has been taken out and it moves with little pressure, very freely, I guess as supposed to from factory.
But the rear one is corroded and moves with pliers and under huge pressure only.

Well it turns out I cannot seem to understand how to take this sensor apart, do you have any ideas? Maybe it was made sealed and is meant to be changed not repaired. Even if that's the case I'll give it a try and make it open

I was really stupid and not thinking clear this morning when I came to a conclusion that the only option for me is to splice it in two with a kitchen knife.![Uhh...](https://www.clublexus.com/forums/images/smilies/1387914497.gif)
When I was almost done and after having a cup of coffee I understood that the upper part of the sensor is detachable ![Stick Out Tongue](https://www.clublexus.com/forums/images/smilies/tongue.gif)
Well inside we see this:

The area in red is the connectors that are completely corroded I would have to replace them with new ones and solder them both to the wires and the scheme itself.

Here is the moving part taken out, I have broken tabs that were holding the thing inside, but that's not a biggie. Basically the moving part moves from side to side just a little, closing either on or another circuit, hence sending different voltage reading to the headlight related ECU. I found all of that out from the manual.![Uhh...](https://www.clublexus.com/forums/images/smilies/1387914497.gif)

Well that's it, I think that's the first ever picture (or not) on the internet of the Lexus GS headlight height sensor taken apart.![Thumb Up](https://www.clublexus.com/forums/images/smilies/thumbsup.gif)

But I still decided to fix it, well you know the rest
![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
There is a front driver side headlight autoleveling sensor as well and the two bushings metal thing attached to it has been squeaking very bad but that's now fixed and all is well.
Nonetheless I highly recommend checking on these sensors before you got out buying bushings, balljoints and what not in attempts to find what went bad and is causing some noise

Well it all started when I have noticed that the sensor bracket is broken, there were no squeaking or anything, xenon has been leveled well and there was no malfunction sign on the dash.
But I still decided to fix it, well you know the rest![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
