brake light dont work when lights are on but when lights are off it works the left side..really pissing me off

Change relay control module Lights Switch

Where is it ??

i would try swapping out the brake pedal switch

I've run across this many times over the years with different cars and it's usually just one bad bulb. Invest in a few new bulbs and change them one at a time (front and rear) until the problem is fixed.

clearly its an electrical issue...are the brake lights the only issue with electrical that ur having?

it either the relay not working work u mint have the wrong light i know ppl change light in there car they buy the wrong ones did u change ur brake light??

i had this problem on my Toyota. it was down to an earthing problem, the bulb holder was tarnished (rust like) on one of the metal contacts. We cleaned the contact and bent it slightly to make sure it did make contact and so far it has cured the problem.
