I hope someone out there can help!
My GS300 has developed a fault with the brake lights, they don't work!
I checked the 20A fuse in the drivers footwell, it is OK.
I checked both bulbs, they are OK.
I removed the under dash panel (with the footwell light & diagnostic socket) to see if I can see anything unusual, nothing I can see, switch moves when the pedal is pressed.
Is there a relay I can check?
My thought is both lights = fuse, relay, switch or wiring.
Any ideas to try and diagnose this dangerous fault?
Cheers,
