I'm from Melbourne, Australia and have a 2004 Nissan Cube Cubic (BGZ11).
Ever since I bought my cube nearly two years ago, the rear left door lock and the drivers door lock sometimes lock and unlock. Over time, the rear left door stopped working, then got used to manually locking the doors.
Back then I had a look to try and see what the issue was but couldn't work it out as it's something to do with the locking motor (solenoid) which I didn't want to remove to take a closer look in case I broke something, plus it looks like a painful job to remove the door locking mechanism.
With the door trims removed, I can see that the motor is trying it's hardest to pull the cable to lock/unlock but it doesn't seem to have that get up and go power to do it's job. So I left it as it is, later finding out this is a common issue with our Cube's. Only fix is to get a second hand unit or a new unit, which can get expensive.
Lately my drivers side door lock was playing up so I was determined to find a fix or
Something that caught my eye a few weeks back when trying to find a solution for this, when I stumbled on a YouTube video of a guy fixing his locking issue in his Nissan Elgrand. Watching the video, it seems the Elgrand has a similar central locking set up as our Cube. Instead of spending a fortune on second hand (that's if you can find any) or even a new one. I was going to see the guys method will work on our cube?
End result? Both lock fixed!
See below how I fixed my door locking issue the alternative way.
Basically we will be using one of the locking motors of the kit to connect inline with the cube's locking cable to assist the lock/unlock. The good thing about this alternative fix is that we will be using the existing wires in the door. For those of you who have installed a central locking kit before will know it's time consuming job, specially the wiring.
Total Cost: $25 AUD + Materials you have at home you can use.
- Central Door Locking Kit, cheapest you can find, try eBay.
- A couple hours of your time (longer depending on your skill level).
Depending on your mechanical skills = Med to High
Don't try to attempt this if you can follow instructions, these instructions will not be step by step but will cover the important things you need to do, the rest you will have to work out yourself.
Once you have received your central door locking kit, put it side for now.
Remove your door trim and the clear plastic cover, carefully make sure not to damage it. I used a stanley knife to slice the black tar glue for easy removal. For this guide I will be doing my REAR LEFT door.
You need to pop out the 3 clips (circled in red) these hold the door wiring harness which you will need to get to.
Carefully open the black plastic cover to reveal the wires, you will notice there will be only two thick wires going to the door lock. These will be the two wires used to power one of the locking unit you purchased for later.
You will need to remove the top cable, to do so, remove the bolt (circled in red) to remove the door handle, if you have a quick look, you will easy work out how to remove the door lock cable.
In this step, be VERY CAREFULL.
Unlike many old cars, old cars tend to use a metal rod for the lock/unlock cable, newer cars tend to use a thin cable inclosed in a cover.
We need to strip back about 2 inches of the plastic coating, to reveal the twisting wires.
Using a pointy tip metal plyers, cut away the twisting metal wires.
