ok since this is such a strange problem to me i'm having trouble searching the problem.

all turn signals work fine
all break lights work fine
its the running lights that don't work

my left light does not turn on when i turn on the lights only when i press the break... i replaced the bulb but same thing whats wrong?

 

if that light comes on with the brakes, it's the bulb. they have 2 elements in them, one that comes on when u turn on the headlights and the other comes on when u put on brakes. the bulb # is 1157.
