when pressing the brake pedal the left turn signal lights come on, on 2002 ford explorer
This is signs of bad bulb on the left side,or you have a bad wire going to one of them on that side.
U think if i change the bulb on the left side signal light is gonna be okay?
That is what i would do first,if that does not fix it check the bulb socket,and wiring on that side.
