Not the fuse. Not the bulbs. Not the brake switch.

Hi,

If the things you mentioned are good and functional, then either you have a broken wire or no ground.

This vehicle isn't offered in the US, so I don't have any wiring schematics to check. However, have you confirmed there is continuity to ground from the light assemblies?

Also, did this happen all at once?

Let me know.

I took my brake switch off and I put my multi tester on the pins of the brake switch and got no power at all.

Hi,

Were you checking the disconnected switch or the wiring connector from the vehicle? If it was the wiring from the vehicle, the power loss must be before the switch. This is where it will get difficult for me to help because I don't have a schematic to trace the wiring.

Let me know.
