how do you fix the brake lights. My lights work bulbs are fine checked all fuses

Hi the tun signals and light work I was also advised to check that box thatss attached to brake

Ok that tells me that the wiring and bulbs are ok. However it can still be the signal light switch that is causing your brake lights not to work! The brake light circuit goes through the sig. light switch before it goes to the rear lights!!! If yo check the switch like greg told you to do in the first answer, and it is ok, then the signal light switch is the only thing left! Hope you get it fixed, may need a mechanic to check this out, hands on. Good luck!

be sure to check wires at brake light switch. bad to break on these.
