Why won't my turn signal work when my running lights are on? but will if the running light switch is off as so will the emergency flashers? I recently changes the whole set of both my front turn signals. running lights work, emergency lights work, turn signals work but only if the light switch on the dash is off.

I pulled a uhoh when i changed the turn signal housing and never disconnected the battery. it seems to be unaffected because all systems work independently, but again, when i turn on the running lights my turn signals refuse to work in the front.

Did you check for voltage and ground at the turn lamp connector, where the bulb plugs in? All turn signals, front or rear?

I found the wiring diagram below. The top wire going to turn bulb is voltage the bottom wire is ground. There could be a ground issue somewhere, maybe the park lamps are using the turn circuit for ground??
