hi i have a bad side marker/running light and it's not coming on i have checked connections and replaced the socket and bulbs but nothing
is there a fuse somewhere maybe??
or where would you look?

My right front turn signal went out. Took it to the dealer thinking it was the bulb but the bulb was good. I ended up taking it to my indie and he had to wire in a jumper wire. I would start with that.

They are on an electronic fuse.

I had the same problem, just replaced the connector end. Tried new bulb's and cleaning the connections and just could not get the bulb to light. Again the final resolution was to replace the bulb holder.
