Brake lights

Evening all,

I’ve got a few issues with my 2013 Grand Picasso. ABS/ESP/Park Brake. Decided to replace the brake switch as it was suggested. Done this however now brake lights don’t work. So put old switch back in and still no lights!

Help!!

I have Lexia and have now diagnosed the main fault to the rear left wheel sensor, I’ll try and buy one tomorrow, however really need brake lights!,

Thanks

Aaron.
