A few people have asked about changing the reversing light switch recently when its been discussed, so thought i'd take some pictures as I did it. Not sure if someone has made abefore, but hey-ho, this may help a couple of people if there isn't one. Really easy job, only takes about 20mins start to finish. Was covered in oil from where the CV boot has split, so could be why it has failed.
How To - Reversing light switch
This is on a Z20LET with F23 gearbox. The switch could be in a different place on other boxes.
First off, jack up the car, get it on a axle stand and remove the passenger side front wheel.
Then locate the switch
And unplug the wiring loom
I then looped the wiring just to double check it was the switch that was faulty and not the wiring/bulbs/fuse etc. With it looped turn on the ignition and check the reversing lights, they should be lit up.
The switch is 19mm and needs a deep socket to remove. I tried with a 3/8 drive and it wouldn't fit as the socket became too narrow to fit over the connector. So you need a 1/2 drive 19mm deep socket. Easier than using a spanner, as there is a notch on the gearbox which makes it very hard to get a spanner in place.
Unscrew the old switch, screw the new one in place and reconnect the wiring.
Just need to check its working, and then refit the wheel - JOB DONE
While the wheel was off I gave the disc a much needed paint, and repainted the calipers as well to get them look a bit fresher.
Also got some oil at the weekend thanks to SRi-T Keithy - Cheers . So decided to swap it and change the filter.
All in all quite a good day, and not bad going for about 2 hours work lol. One less job that needs doing before the MOT
