Fiat Stilo JTD

[Ted Bear]

Any advice please. The reverse lights are not working so I changed the reverse switch, still not working !! I have checked the new and old switch and they are working when I press the plunger on the switch but when the switch is fitted into the gear box it’s not working. Any help or advice please.

Do you have 12v at one of the wires going to the switch? Also, and it sounds daft, have you checked the bulb(s)?

[Ted Bear]

Yes, bulbs are working, I connected the wiring before fitting the switch into the gear box, pressed the plunger and the lights work. Fit the switch into the gear box, connect the wiring, put the car into reverse and the lights do not work.

So, in other words, you are saying that whatever it is that mechanically makes contact with the switch to operate it, isn't.

You need to see if you can see what that is.

Agreed, best way to do that is probably remove the switch and see if you can see any movement down the hole when someone engages reverse. May be a pattern switch and not sat all the way down into its fitting?
