Reverse lights no worky ??

[MattyGreg05]

Fitted a new switch today ... we have lights

Might sound like a stupid question but if I remove the housing on the gearbox to replace the reverse light switch will any oil etc come flooding out?

You don’t need to remove anything but the switch, and no oil will fall out .
The switch unscrews from the housing

Ahh I see Mocki. I thought it was housed in a housing. I even bought a new gasket to replace it.

it is in a hosuing but it is bolted into that hosuing which is bolted into the gearbox. just unbolt the switch, nothing else

If it's the same as mine;
You need to take out the switch by the gearbox (with the twin spade connector).
Give it a clean and refit but just do it up hand tight then tighten slowly while in reverse until the light goes on.

Failing that, remove the washer and tighten it

Is this the switch and cable?

yes that is the one, if you pull the plug off and bridge the connections your reverse light should illuminate, if it does then it's a fault with the switch/actuation of the switch, if it doesn't it's a wiring issue/fuse/bulb fault

Pulled it off. Gave it a scratch. Gave it a wiggle. Lights worked. Spot of corrosion on contacts.

I then went to augment reversing lights with LED spots. Forgot to isolate and blew the fuse (#15 if I recall from last night). Schoolboy error.

I had the same issue for a few months, sometimes it worked, sometimes it didn't. I knew for sure that the problem was in the sensor, shorting it would make lights switch on. Removing the washer in the sensor worked for a while, but last week it stopped working again.

Checked the sensor with a multimeter and it was kaput. Replacing resolved the issue, they are relatively cheap and easy to find.
I installed a reverse camera, since it connects to the reverse light I will know immediately if issue re-occurs.

Mine's given up the ghost as well so I suspect I've got the same issue. And I've got a dash cam with reversing camera so I'll be doing the same as you!

I presume that's seeing if it closes the circuit when in reverse?
