Parking lights and side markers won't turn on
It seems it's always something. Yesterday I turned on my parking lights as I normally do when driving just before dusk. The left side all went on (driver side) but the right side didn't. Also noticed the right side marker lights didn't illuminate either. Only thing I have done lately is replaced one of the side marker lights with a new bulb from RN (fit perfectly and has worked for a week since).
Adding to this is if I put on the Hazard switch all the parking lights and side marker lights go on but the right side that was not going on before and side marker lights all "blink" in unison with the turn signals but the left side do not blink (as they shouldn't).
I should add the turn signals, headlights and brake lights on all sides work through all this.
Thoughts before dig into this?
