So i swopped the two bulb holders over but no change.
2014 ford focus brake light bulb fault.
Drove the car around today and it was fine all day.
We have the best products at the right price.
Equip cars trucks suvs with 2014 ford focus brake light mini bulb from autozone.
I have a focus 2010.
No bulb fault notification anyway.
Made a stop just about an hour ago and the notification came up again.
The front indicator does not work as well as right side brake light.
Sure enough i caught the left brake light out this time with the parking filament working fine.
I recently got a brake lamp fault.
The light changes green and about three seconds into my acceleration around 2nd or 3rd gear i hear the distinctly annoying beeping noise coming from the dash and the all too familiar fault code message appear on the driver display.
So i went to replace the oem bulb with a fresh bosch 3157 bulb from amazon.
But 10 minutes later when i got home the brake light was working fine again.
Even with a new bulb i still get the fault.
The driver side tail light works but the brake light doesn t light up when the brake pedal is pushed.
While changing all my front bulbs to osrams cool blues i changed the indicator bulb but it didn t work.
Hi i have sorted this problem on my 99 focus ghia check both your tail light bulbs someone put the wrong bulb in and i had the exact same problems you described the bulb for brake tail light has two steel connecters and and all other bulbs have one i put proper bulb in and the problem disappeared now lights working perfect and sidelights dont come on now when i brake change both brake tail.
