W Reg Ford Focus. Rear number plate and brake lights not working. Any suggestions

check the relays please

If bulbs are definetly ok you can look behind trim on the left side in the boot, which covers the space between the boot floor and the window, you are looking for a green/red wire in a connector. this is the power cable which supplies both rear side mounted brake lights. You should check for voltage at this wire when pedal depressed. If no voltage you would need to trace this back to where the wire is joined in the loom as it feeds off the wire which supplies the high mounted brake light and you have stated that this works. Would still double check bulbs first though if you did'nt replace them. Hope this helps.

what the ?? is a Y reg focus is it a special model or something ,please state year we dont all live in immigrants haven formally known as UK ,these two components are on different fuses anyway,rear wiper check the rubber boot from the car body to the rear door ,wires get damaged in here ,ciggy lighter ?? take it out and have a look at the earth and or wiring plug ,they overheat and cook if used for lighting ciggys

thats BAD....ck brakes and wheel bearings for rear. ASAP

Change the flasher relay! Points frozen on one side of flasher!

brake light switch, at the pedal

yes it sounds like the turn signal switch is defective, the brake lights go through that switch as well.

You  probably have a frayed wire touching something metal (short to ground) check your wiring, check your grounds.

my suggestion is go to a dismantler get another belt and ask or watch him.and no its not hard
