Tailgate won't open? - RENAULT Laguna 3 - How to fix tailgate latch
HTML-код
- Опубликовано: 14 апр 2020
- If the tailgate on your car won't open the problem could be in a couple of things. In this video, we show how you can open the trunk door from the inside using just a screwdriver. Also, on our Renault Laguna 3, we inspected the latch, locking mechanism and actuator motor to see what can be broken and to prevent the tailgate from opening. You can see how some of these things can be tested so you don't replace the parts which are still working on your tailgate. Have you had similar problems? Tell us in a comment and share how you fixed it.

Found your troubleshooting and disassembly guide. It is a little bit different on a Renault Megane though, there are 2 more T20 screws to unscrew beneath the corner surface panels before you can take of the big panel. So make sure not to try and remove it by force before unscrewing these. Anyway, this guide enabled me to troubleshoot and in my case everything checked out except for the actual trunk switch which is a normally open switch. When shorting the contacts in the connector itself using a bare wire, it popped open the trunk. Disassembled the switch and it had a bunch of water in it. I'm guessing condensation because the rubbers and case of the switch were all intact... Dried it completely, sanded off and cleaned the contact surfaces of the copper switch mechanism and it is now making proper contact and working again. I'm guessing it will last me at least several months if not years, if the switch casing really isn't damaged. Hope this explanation helps others as well if they are facing the same problem. Cheers.
@Nick Vanbaelen Hi. Thank you for sharing your experience and for describing it so well. It is nice when someone does so in order to make the life easier for someone who will face the same problem. We wish you to have no more problems with the switch and once again thanks for watching and sharing. Cheers.
Best video I've seen on RUclips regarding this problem. I have a clio with a boot opening problem hopefully this will help pin point the problem
Thank you very much. We are hoping you will solve your problem. Good luck!
Thank you cindly for the tips! ❤😊
You are welcome. Thanks for watching!
Works well. After I opened boot door I used some silicone oil because mechanism was moving very hard.
Great. Thanks for watching!
Very good, usefull video! Thank you for making that! Hvala! ;)
Thank you for watching and for your feedback! :)
Odličan video, meni se par puta dogodilo da se prtljaznik otvori sam od sebe (Clio MK3), pretpostavljam da je problem u samome prekidaču, srećom da sam naletio i na vaš video o popravci prekidaca pa cu se malo pozabaviti s tim.
Super, nadamo se da će pomoći. Javi kako je prošlo i hvala na gledanju!
I had the same problem on my Megane 3 hatchback.I used WD 40 and it worked!
Well WD40 is probably the worlds greatest invention isn't it? :)
WD40 which part ?
Wow. Big thank you!
Glad it helped. Thank you for watching!
Nice video :)
Thank you!
You guys make great videos!
Thanks for that :)
Do you have a video for replacing the door lock on the passenger side?
Mine sometimes won't open from the outside. Of course on the Laguna 3
Glad you like our videos. Thank you for watching.!
We don't have video for lock replacement yet. Can you give us more details, does it unlock when you press it on the keycard, or it doesn't unlock keyless when you pull the door handle?
@@BbrosAuto the outer door handle doesn't work, and you don't her the "locking engine" (sry don't know the English word :D) work.
Our best guess is that the actuator motor is broken if you don't hear the mechanism as you try to unlock.
Ja imam problem kod megane 3 nece gepek da se otvori microprekidac ispravan kako cu znati jeli do brave te elektronske na nju kad fizicki masu dovedem okine kao da je ispravna svasta
Vrlo precizno i jasno objašnjeno. Imam megana ali mi je baš pomoglo ovo, pogotovo oko elektronike. To jest, oko proveravanja brave. Sve kontakte na bravi i u prekidaču sam očistio i isprskao conatact klinerom. Ali problem i dalje postoji. Nije prekidač, to sam eliminisao. Ali kada spojim bravu na njen džek, čuje se manje više konstantno zujanje. Da li možda znate šta bi moglo biti dalje ? Verovatno nešto sa elektronikom.
Great video, I do not have 12V on 1-2 pins of the car cable. On button press there is 1.5V on pins 1-3. Where should be the find this fuse and how to check cabling? I have Megane 2 2008, kombi/estate version.
Hi, thank you. We haven't had an opportunity to do this on Megane 2, but we have found this fuse box diagram for Renault Megane 2 online and this is the link to it:
fusesdiagram.com/renault/fuses-and-relay-renault-megane-2.html#:~:text=Power%20fuses%20under%20the%20hood,the%20Protection%20and%20Commutation%20Unit.
Cabling you can check with a measuring instrument, which you already did, or you can look at the places where wires are connected and in places where wires are exposed to movements such as the place between the trunk door and the rest of the chassis. If there is an issue with wiring these are the places to look.
Did you check the actuator motor, and which contacts on the connector are for bringing power to him?
Thanks
Welcome
Great video! What was failing in your case? Wasn't the little actuator motor in its place, so the worm gears weren't attached thus keeping the mechanism from getting the latch opened?
Thank you. We actually got a couple of questions on Facebook about this so we just tried to make a video about what could potentialy be the problem. On this car everything was working actually :) Did you have problems with tailgate on your car?
@@BbrosAuto wow, great informational video then! Actually I was trying to do some research on the reliability of the Laguna III and Megane III, that's why I ended up at your channel. Subscribed, because it has really useful stuff! Keep up the great work!
@@wody21 That means a lot, thank you! We have a lot of ideas and videos in production. Regarding the Laguna III and Megane III, we have both in our family, and we're really happy with them. 1.5 dci runs really well, there was no big isuess with either of models, but most of all we like how comfortable these cars are and their character.
I have this problem on my mk3 Scneic 2014 which look identical to your Laguna, if it is not the switch or locking mechanism what else could it be? I assume not a fuse as this would control all the doors etc? cheers
Yes James, one fuse is for all doors. Maybe the problem is in the wiring or reley.
Taman i kod mene isti problem na R, s, - u, kad sam otvorio prekidač unutra kontakti bili zeleni, ja ih ocistio, izbrusio na fino, i vratio sve nazad, nadam se da ce sad raditi, no voda i veliki problem, takoder i bravicu sam promjenio, i provjerio kablove na pregibu haibe(jer i tamo zna bit problem).. Uglavnom nadam se da ce raditi.. sad..
Sretno, moralo bi sad raditi dobro. Hvala na gledanju i dijeljenju iskustva!
Nice video. At 03:30 you check the voltage in pins 3 and 4,correct? What should the voltage be in pins 1 and 2?
Thanks George. Yes, the way we are holding it in the video we can call them as you said. So there should be no voltage between 1 and 2 because these contacts are for indication if the door is open or closed. These two contacts are not connected to the actuator motor and they are not responsible for opening the door.
@@BbrosAuto I am asking about the voltage because I have a Renault Megane III with a problematic tailgate latch and I am trying to figure out which side is which. In my case,when the trunk is open I have 12V in pins 1 and 2,and there is no voltage in pins 3 and 4. So maybe there should be voltage in pins 1 and 2 when the trunk is open(to indicate,as you said,if the door is open or not) and I should have voltage on pins 3 and 4 when I press the button?
Later in the video you can see we took it apart and test out which one is which. That way you can be sure which are the motor contacts and should have voltage.
how to adjust the Tailgate?? Help please 🤗🤗
My clio door trunks not closed,what the problem
Thank you for this video!
I have clio 3 and my problem is, there are no 12V on first 2 pin after pressing the switch. The switch itself works. There is 6,5V - 7V on green and black wires to the switch. Motor works as we tried it directly on battery. I checked all fuses which I found, but all seems fine.
Do you have any idea what could be the problem?
Thank you!
Hi. It could be that one of the relays is broken. But we can't know for sure. Thank you for watching!
N
Thanks for sharing, could you please guide where is rally
@Anand Somani Hi. Relay is in the same place where the fuses are. That is on the left from the steering wheel, behind a little storage compartment. Thank you for watching.
@@BbrosAuto thanks for response. Not sure which is relay for tailgate. Is separate relay for tailgate?
@Anand Somani We think it is separate because there is an option just to unlock the boot door, but also not sure which one it is.
Hi, my dad's Megane 2 had this problem for at least 1 year now, when I thought I fixed the wiring in the upper harness, it worked for a month or so, then it failed again. Do you have by any chance a wiring diagram or a video fix for the harness in the upper part of the trunk - since I think it is still the problem. Thanks in advance!
@ drazman9. Hi, we are sorry but we don't have a wiring diagram for Megane 2. We have searched online and asked a few friends but we didn't have any luck finding it. We hope you will manage to fix this problem.
@@BbrosAuto Hi, thanks for looking anyways! I hope I can manage if I find time again.
My tailgaite do make some noise every time i drive in bad road or if I do drive to uneven road. How to do ti fix it?
By the locking hook positioning
Thanks! This just saved me :)
You're welcome. We're glad it helped
I have a Laguna 2 and the problem was with the locking hook position, you can positioning by unscrew the fixing bolts and move it inside or outside to left or right for the ideal position I hope it will help you
@Robert Rusz Thank you for sharing your experience.
I think I have the same problem in that the locking hook won't latch when I push the tailgate down into the closed position, no matter how much force I use to push down the tailgate. Which are the fixing bolts you unscrewed to get the ideal position?
@@Pequinito torx i can't remember the size, i think 20

I have a Megane 3, tailgate won't open there is no sound of it opening along when pressing the button for the doors. Do you think this is a wiring issue?
It could easily be the wiring, but we can't know for sure.
My issues with the booth opening are intermittent, sometimes it works fine, sometimes I can hear the switch clicking but actuator is not responding and sometimes the actuator goes on its own multiple times on repeat. The switch was freezed in place on low temperatures couple of times but it worked fine after it melted. As far as I can tell without disassembly the switch is clicking fine. Any idea what the issue might be?
I have the same issue, sometimes it work, sometimes it doesn't. Dis you manage to dins the root cause?
@@AlexandruHasegan Finally I found some time to pop out the switch and I've found it was full of black liquid, probably dirty water. Not sure how it got in there though, maybe the switch was not seated properly because it has a rubber part that should seal the bottom part of the switch when seated correctly. I've cleaned insides and added some lithium grease to rubber to hopefully help to seal it moving forward.
Dirty water could cause low resistance between switch contacts (occasional ghost clicking).
@@semiRockethrThank you very much for your insights. Will try to make time to take out the switch.
Promjenio dugme i bravu al i dalje ne radi di se nalazi osigurac ? Moj je megane 2 jedino mi je ostalo osigurac i zice pogledat
Ne znam, nisam imao Megane 2.
Jesi li rijesio problem sta je bilo i ja imam upravo taj problem molim vas odgovorite ne mogu otvorit gepek
