Hi all, hoping someone can give me some guidance. I noticed Mrs Mac's lower brake lights weren't working the other night so thought I'd have a go today at sorting it. I've changed the bulbs for 2 different types, checked the switch above the brake pedal and even had a look at what I think is the right fuse/ swapped it for new and original. The lower brake lights will not come on but the middle/ top one does. All other lights are working fine. I've tried single and dual filament bulbs but I'm out of ideas now. Does anyone have any advice? I'm not mechanically minded but will have a go.
