Self leveling light problem

Hi guys, 

I've tried to find something on the form but unfortunately I wasn't able to find someone with my problem.

Long story short, I'm not using a lot my car ,so most of the time is parked in the garage. Last time everything was working fine, few days ago I went for a ride and I noticed something wrong with the headlight. When I turned them on instead to leveling at the right position they went all the way down.

Actually I know there's somewhere in the back some sensor can automatically level the headlight, but unfortunately I have no idea where is and if the problem is relative to it.

Any help would be great.

Cheers

PS. The car is a CPV35 2006

PS2 sorry for my bad English.

Does it have a headlight height switch? If not, then check these

Strange that both drop, possible the height controller box died. You should be able to disconnect the motors on the headlights if so.

Thanks mate, I think I have found the part.5911885d5b5fc_IMG_20170509_1755341.thumb.jpg.72d54eec8d1f6426616cc00303748514.jpg

I tried to disconnect it and move it manually, but the headlights weren't moving.

I tried to disconnect the plug with the lights off, and when I turned the lights on, the motors didn't turn on and didn't lower the lights.  When I put the plug, back in, the motors lowered the lights down.

What do you think? Thanks for any suggestions or advice!

I'd need to get a look at a schematic to understand what's going on but I'd imagine there's a sensor, control circuit and a stepper motor. One of those three components will have failed. If it's an optical sensor, it might just need a clean with isopropyl alcohol. If it's a mechanical sensor, it'll either need a clean or replacement. If it's the control circuit, easiest approach would be to replace it but if it's just a dried out or shorted capacitor, that can probably be cheaply sorted out. If it's the stepper motor, you can determine that by feeding the appropriate pins with 12V to see if you get any movement out of it.

Again, without a schematic, hard to be sure where to begin with the diagnosis past the obvious mechanical bits.

    • Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
    • This is going to be a mid week evening cruise. Come along and join us for a drive out to Palm Beach. This is a change of event plans after talking to some of the older members of the club. SAU NSW is planning on hitting Old Pac again shortly, stay tuned for details. When: Thursday 26th of June Time: 7:30pm meet/8:00pm departure/10:00pm finish Meet: Spit West Car Park / Spit Rd Mosman NSW 2088 Destination: Palm Beach Public Parking / 16 Ocean Rd Palm Beach NSW 2108 Up to date information as always can be found on the events page of our website, the link for this event is https://www.saunsw.com.au/events/palm-beach-cruise There will be a lead and follow car so no one should get lost. If you would like to attend or bring others along please put your name down and a +1 as numbers will be needed prior! This is NOT a race and we will all be adhering to all road rules. If this is what you want please come to one of our track days. This is an official SAUNSW event and will be run under a Motorsport Australia permit. One of the things that really sets our club apart is our commitment to being true enthusiasts. When on normal roads we strive to maintain good relations with the authorities as well as the public in general. When attending one of Skylines Australia NSW events please try to: • Be aware of surrounding environment and act accordingly. • Drive courteously on the state’s roads as a true enthusiast should. • Understand how important it is to maintain the good name of SAU:NSW and thus, treat others accordingly. • Any misbehavior will not be tolerated and you will be asked to leave. Thanks guys and hope to see you there!
    • Good time for a carbon roof  
    • Not in any way aroused by any of those, except maybe the big AMGs. And that would break my never a Euro, ever, rule.
