Brake lights staying on

[LCIOM]

Hello,

Hoping someone can help.

When I turn my lights on, the brake lights of my 2015 Fiesta ST stay on. I'm thinking this is something that has happened recently because it has been pointed out by 2 different people in the last week. 

Any ideas?

Thank you

Check your brake light switch

Looks like a little plunger that goes into a little box with an electrical connector on it. Be in the footwell on the brake pedal

Disconnect it and if your brake lights go out that's the problem, either a faulty switch or it's not triggering correctly, I don't know if these are adjustable in our cars

Check it first and go from there. If it's the switch it's easy to test the switch, just plug it back in and operate the plunger by hand
