Great video, except one minor item, the broken wire should be soldered and sealed with shrink tube.

[@RichardCuico]

thanks for providing the proper long term solution. I'm not a professional so I just offered the easiest quick fix method.

[@crunchylicenseplates9008]

I wanted to comment that my W220 did not have this part at all. Your video covers replacing Part #220-820-06-21 which is available as an MB Part currently available for about $70 or as a cheap chinese aftermarket part for about $15. My 2000 (S430) W220 had a different fixture with no incandescent bulb, only LED, part #254-138 / #254-136 which is no longer available. The release lever is on the bottom left not at the top as shown in your video. There's another video on YT covering how to remove the LED panel and resolder all the connections without having to spend any money to restore functionality.

[@nordemoniac]

The best solution is heat shrink with glue in it. I’m gonna remove my mirror and check. Had problems with blinker last year, went away, and is now back again. I have also lost heat in the same mirror. Sounds more like wires than a faulty component. Thanks for the video, gonna disassemble and see if any wires have lost their insulation.

[@ajmach54j84]

Yes a better longer term fix for sure....

[@nordemoniac]

Blinker seems to be defective, but after removing the wire wrapping, I found a cut wire for the heated mirror. Should be an easy fix. Seems like water gets in under the wire insulation, and it corrodes over time. Wouldn’t be a problem if MB used heat shrink on terminals.

[@V12Smooth84]

Thank you! I just replaced mine. 2004 S600 still going strong in 2024 :)

[@TheNewMexicoMan]

Six years later and this is still helping out those who need to know how to replace the turn signal. This install was easy thanks to your instruction!

[@heikg]

Yep, helping people not move onto the new junk they call cars.

[@andrewcahill2991]

Crazy lol I recently bought a 2003 s500 so far i love the car. I bought from a one owner elderly couple who bought it in 2003. They kept the car in immaculate condition i bought it for 5500. But my driver side mirror indicator doesn’t work

[@TheNewMexicoMan]

@@andrewcahill2991 The car in 2003 cost around $80,000 new. I bought my 2006 S500 in 2015 for $9,000 US dollars and found the window sticker saying it cost someone $86,000 new.

[@donwood4216]

This KZbin video was one of the most information and helpful repairs I have ever viewed. Many many thanks to you!!!! EXCELLENT!!!!!

[@RichardCuico]

no problem! I'm glad it helped

[@cjlomax2156]

Nice work! You should solder that wire and wrap it with a proper sleeve! Good content bro!

[@robertnelson860]

THANK YOU!! Found a broken wire just where you suggested. Fixed it now, works great

[@richardgaskins4464]

You are THE MAN!!!! I follow your instructions and was done in less than 5 minutes. I got the light off Ebay for about 45 bucks. I cant imaging how much the dealer would have wanted to do this.

[@RichardCuico]

Glad I was able to help you out!

[@paulmorrison2059]

Great job. Thank you. You made it easy: very clear step by step and excellent camera work so that we could see everything you were talking about and doing. Keep up the great work.

[@ajmach54j84]

Very well done. Pictures made sense and you explained when to be careful and showed why. I like the fact that you covered problematic issue with wires. That will save a bunch of people a lot of time Thank you Richard...

[@RichardCuico]

No problem and I'm glad I was able to help!

[@gjamesd1]

Great job! I wish I had seen your video before buying a CHEAP imitation mirror that hadn't worked right since I got it. I will go to a wrecking yard and try to find one and follow the well documented instructions you have made!!!

[@RichardCuico]

[@samuelm714]

Thanks for doing this video. It has helped me a lot! ❤

[@jbour1896]

very helpful the cheap ebay replacements apparently draw less power than the OEM so they were triggering a fault message for the mirror signal light so I added a small dash light bulb spliced in to use more power and simply put it inside the housing as there is plenty of room

[@rmahabier4150]

Good work, nice video. Thanks for sharing! Greeting from Holland

[@JorgeRamos-km9ji]

Richard you fixed it the easy way thank you

[@aal5488]

[@Proximax9]

thanks for this! couldnt figure out how to open the mirror housing. my left turn signal works only in cold weather so I assume it's one of the wires somewhere... now I know where to start looking :)

[@fazalmahmood534]

Good job

[@muhammadaljisr7427]

Very clear and well done. You took care of the small details skipped by many others. I have a related question though. A nasty fellow folded my mirror by force and broke the mechanism. It's now loose, folds due to wind when I'm driving. How to fix that?

[@RichardCuico]

I've never encountered a problem like that before but I can think of two ways you can fix it. First try checking the spring which you can see at 5:57 in the video. Maybe that spring became undone and all you have to do is reattach it. The second would probably be the motor. You can check this by seeing if the side mirrors still fold electronically from both sides. If the side that is broken doesn't fold, then you'll have to replace that or components within the motor that control the side mirror.

[@siphilipe]

Well done. If just one led goes down, can the whole light blinks very fast?

[@ACk3v]

Thank you 😊

[@hamidkessab8126]

Thank you for the great video, after checking all the wiring behind the left visor , i did not find any broken or cut wires . my question is there a fuse or relay ? that controls that Left side mirror turn signal. i have a 2006 S500 and all lights work but this left turn signal just stopped working. tHANK YOU for taking the time ..

[@RichardCuico]

hard to say what the real problem is then. If there isn't powering going to the signal then it might be a wire deeper in. Maybe try tugging them a bit to see if they easily get pulled out of the housing. Another reason may be the bulbs finally giving out.

[@MrBjornbjork]

thanks Rich

Is the housing used for this turn signal the same for Merc CLK240 (W209)? Mine Shattered and needs replacing but the light works fine..

[@piperoberdiear6690]

Thank you for that info very helpful.I need info on installing a rearview mirror on my S430.can you help?

I haven't ran into that problem myself yet so unfortunately I can't help you. There should be other videos and tutorials showing how to do it though

[@sinvalginete7089]

um muito bom os ensinamentos .

[@bettabegoodjr2104]

Is there a fuse that controls these side mirrior blinkers?? I just bought a 2005 c240 4matic . All the blinkers work around the car besides the two on the rear side mirrors. Does that sound like a fuse problem? Or have the LEDS gone bad?

[@boroslaslo]

Do you know if its possible to replace in prefacelift side marker with the facelift one if the cover remains ?

[@clifbenford9403]

Nice job...

[@RichardCuico]

thanks you sir!

[@edthayres9175]

I replaced the old lens with a new OEM parts. I continue to get the fast flashing blinker in the dash and an error message. I read somewhere it may now be a wire between the mirror and the door?

[@edthayres9175]

Outstanding and well done. Thank you for sharing this. Am I to understand the entire clear lens has to be replaced to get the turn signal to work again?

[@RichardCuico]

glad I was able to help! Not to sure about your question though. Do you mind elaborating?

[@edthayres9175]

@@RichardCuico I'm sorry Richard.....spell check didn't catch lens, instead it put Tense... Ugh.... I answered my own question with the lens. I received it yesterday and I will install it today. I was hoping it was just a simple bulb but as I discovered,I do have to replace the entire lens assembly.

thank you

[@johnreddington4393]

Hi there I have a 2001 Mercedes s320 and it has the function for the mirrors to fold in when I lock the car with the key fob I have the function turned on in the car but it doesn’t seem to work just wondered if you had any ideas as to what it might be I have checked the fuse and seems fine and also tried resetting the fob but still no joy I’d be very appreciated for any response you might have

[@joe816]

Thanks bud

[@mousaabdulateef9205]

رائع.....شكرا جزيلا

[@krzysztofgraban]

Good job! These lights use diode so they should work or be dead totally. My mirror blinkers are very dim. I don't think it's the cables' fault because they are equally dim. Maybe there is a way to fix it without buying new ones?

What are the best HID lights to put on a S430

[@hamidahismail7600]

there's a camera below side mirror is that a blind spot assist?

[@Lord_montu999]

Definitely before you another check the connection because my passenger seemed to have been struck. I opened the and reconnected the harness the light. I left the harness unseated the harness mounting bracket so it was easier to reconnect with a lower likelihood of disconnecting again.

Hopefully it just turns out to be one of the wires which is an easy fix! If not the process should be very similar. Best of luck!

[@jaeikjung4505]

It is hard to find the part with the seperate light bulb attached for downward lighting. Is it okay to use one without the downward lighting bulb?

[@rsmcustomguitars1480]

Hi Richard, Great vid. Thank you. Can I ask you where to locate the fuse responsible for the driver door control module? Its either the fuse that has blown or I need a new module, as there is no power to any windows or heated seats etc. Thanks again. Rob.

[@RichardCuico]

Sorry man I’m not too sure where the fuse box is since I’ve never had to replace one myself yet. Try pelicanparts or mbworld. Usually they have some awesome tutorials on that website.

[@rsmcustomguitars1480]

Ok thanks Richard. I will have a look. All the best.

[@jamesschultz]

Is it possible for you to make a video on the side markers? I have “1 malfunction” on my ‘03 S430 because the bulb is dead but I have no idea how to replace it, thank you!
