Brake lights not working
Hi All,
None of my brake lights appear to work. I checked a few things and got them to work for a couple of minutes then nothing. Changed the light failure relay (the round one) in the dash, again worked for a bit then nothing. I'm getting a brake pedal switch as soon as I can as that seems to be the next step but is there anything else I can check in the meantime? All the bulbs work fine.

My brake pedal switch just needed adjusting. It had slipped back when I replaced the cover under steering wheel

I cant remember exactly what i did but i seem to remember pulling or pushing the whole switch in or out ( sorry to be so vague ) and that fixed it. Along the lines of one way they didn't work at all and they other way they stayed on all the time and somewhere in the middle they worked fine
Hope that makes some kind of sense

Right this is weird. I pulled the switch out and tested it, it works as there is continuity across the contacts when it’s not pressed in and no continuity when it is pressed in (ie brake not pressed)
What to check now? I’ve changed the fuses and the relay.

Try putting switch back in and moving forwards and backwards and see if you can get lights to work. An assistant or garage door reflection helps
