I've lost power to my cornering lights. I still get both turn signals but I get no power to the cornering lights. I cleaned all of my grounds. Is there a relay or a switch that typically goes bad?
Cornering lamps are powered off their own switch in the turn-hazard assembly.
Check the harmonica connector on the right side of the steering column for an output right turn is a black wire pin A on it, left turn is the orange wire Pin B on that connector.
Parking/head lamps must be on for them to work.
The Brown wire Pin C is the feed to their switch from the parking lamp switch on the same connector. Check for +12 there with the light switch on.
