Max, thanks for your very easy instructions. I did exactly what you said and it worked beautifully. Also saved me £100 for the labour costs that Nissan wanted to charge me!
I have just needed to replace the switch for our Micra, sadly the problem returned. What I did find is that water ingress happens over time due to the gap around the top of the housing that the switch fits in and the body of the car. When I removed the old switch I found several drops of water where the switch would sit within the housing. I ended up buying a complete OEM switch from eBay, cheaper than at the dealers. When I fitted the new one I first applied a bead of silicone sealant around the inside edge of the housing and once bolted into place another bead running over the top, between the hosing and the car body. Clear sealant looks fine and water will now run around and over than down and into the newly fitted switch. The old switch I'll have a go some time, perhaps, at replacing the actual switch itself, rather than the full unit, with the one that I had previously bought for a couple of quid.
In my experience it’s nearly always the wiring from the chassis into the boot and rubs through in the flexible duct But they are also prone to moisture ingress as you say! Good cars but this is just one common failure in them
Thanks for the video.. Mine is constantly clicking and obviously opening at the same time.. Once I separate the plug inside, it stops, and will stay closed… Would this be that boot switch that you changed?? Thanks
You may need to check the continuity of the wires from the plug with the corresponding coloured wire under the steering wheel to the right hand side to verify the circuitry is OK but yes it is the kind of thing a faulty switch could cause
From where did you bought those replacement parts? I couldn't find one in Sri Lanka. My sensor button cover was broken and the switch is water damaged. So, can't use the boot door lock to unlock the car. :(
Max Attack yep. I know.... I don’t have the technical knowledge to find the exact button or to solder it. Hopefully someone might make a review on that. Anyway the car is made on 2004. Its almost spent its golden years i guess. Anyway, thanks for the review. Cheers
Hi Indunil i had the same problem. I got the parts from Jayasiri Motors Mawanalla. Was just going through the videos to fix it on my own. The whole unit was Rs.6,500.00
Hi Max, I have the switch on my driver's door broken and I'm looking to replace it. Is the fix similar? Can I just get any of those switches and replace on the handle from the driver's door? Thanks in advance,
For a drivers door you need to make sure you get the right handle since some models come with keyless entry, sadly the process is very different and I don't have a video for it but essentially you need to remove the door card to access to mechanism, be careful not to break the half-moon plastic insert clips on the I side handle if that makes sense... It is a different switch to the rear boot too
@@maxautouk That's extremely helpful. Do you know if at least the switches from the door handles are interchangeable? i.e. if I get the left handle I can take the switch out and replace it on the right handle? Cheers
It's hard for me to picture it without seeing it in person but if I remember correctly you need to remove the inner door card and then on the side of the door there is a black plastic cover which you need to remove, it is i line with the handle. There is a security torx screw in there thay you need to remove then the handle will be able to come out. If it is the handle that is broken there is no switch it's just a mechanical mechanism. If the issue is with your central locking you may have other harder to diagnose issues.
@@maxautouk Actually my issue is quite simple, the "keyless switch/button" from the driver's door is physically broken. All the rest works perfectly. I pretty much just need to take the handle out and put a new switch/button - same as you did in your video but for the door handle.
Quick update as it could be helpful to someone else: the keyless switches in the handles (driver/passenger) are the same. I got a passenger handle, took the switch out and used it to replace my broken driver switch. These switches are different to the one in the tailgate though.
Hi, not sure if you'll see this but I am having heaps of trouble getting that little plug in at the end. It just doesn't slide and click in like yours did. Any suggestions ? Thanks so much
@@maxautouk Thanks so much for replying and for your fantastic video.. it was really helpful. It looks like things *should* line up but for some reason it's not. I got it off eBay but it's not a genuine Nissan part, only a compatible one and the only one that seems to be available across the board at the moment (searching for the part brings up countless ones with the same picture). I tried the old plug and it slides and clicks in no problem. :S
Thanks for the video on the switch replacement. Have you thought about dismantling the faulty switch and replace the actual faulty one with a switch like this.... www.ebay.co.uk/itm/254472076068 which can be fixed into position and the wires soldered on The switch is about 1.50 from ebay, as shown. I'm going to give that a go, if I need to as our boot lid has started to auto open itself on our K12.
For the cost of the part and my labour to repair it there wouldn't be much in it for my customers and the new part means I can send them away with a two year warranty at least which is why I opt to replace the entire unit. This is such a good idea, come back and let us all know how it went!
@@maxautouk Yeah I can understand what you mean. I suppose from a DIY situation it would be the cheaper option without a concern over warranty. I am hopeful that after cleaning up the unit, maybe water ingress(?), then ours will be ok. If not I'll replace the switch, it should have arrived by then, and see how it goes. For £1.50 it will be worth a go. If I have to change it I'll post back.
@@markus7643 What I did was to reveal the switch in situ by removing the facia panel from the boot. Whilst waiting for the two switches arrive I decided to apply liberal amounts of WD40 to see if that would help. Amazingly after the second or so application the switch started to work without any further issues. I still have the two switches but surprisingly I have not needed to use them. Good luck
The WD in WD40 stands for water displacement so I wonder if it's just moisture that prevents the switch from working properly... Thanks for sharing your fix, very interesting!

Good information thanks for sharing, the ones I have replaced have a damaged internal switch but no signs of water ingress so this is good to know
I read online its nearly always water related.

Just double check the plug is totally clean, make sure the tabs are lining up and double check the two pieces have same number of pins and shape

You can cut the plug off your old one and connect it to your loom if worst comes to the worst, at least then you can fit it
@@maxautouk Yeah I think I'll have to.. Thanks mate
Hope you got this sorted eventually
I replaced switch witch new one and still not work. Lock itself does work when I bridge two metal pins inside white connector. What can be wrong?
The wiring in the boot loom is a common failure point
@@maxautouk The new switch was faulty. Solved problem buying another one
@@bender22222 nice find
Be careful my fault switch was draining the battery down.
Yes an internal fault in the switch can cause a parasitic draw if the circuit stays completed
