*UPDATED*Weird Front Turn Signal Shenanigans

[wheeee32]

Okay so initially this started with the passenger turn signal giving the quick flash. I changed the bulb. Same issue remains. I notice that the drivers side parking light doesn’t come on but the turn signal side works just fine. The passenger side parking light doesn’t comes on. I tried the hazard switch and I have normal flashing indicated but the passenger side turn signal does not come on. I tried a new multifunction switch. Issue still remains. Anyone ran into this issue yet? I’m going to dig for the schematic/wiring diagram and start wire chasing.

I ran into it with the left turn signal. The ground wire rusted through somewhere between the housing and the ground point behind the headlight. I ran a new ground wire and it works again. A multimeter goes a long way to identifying which wires have continuity and which do not. The wiring diagram you found will help a ton as well, figuring out which wire goes where.

Yeah based off the weirdness of it I was thinking ground before I even started looking for the wiring diagram. I’ll reply back once I find the bad actor.

Okay I see on 8W-52-5 and -6 of the schematic the ground for both. Looks like it might be close to the right fog light.

Found it! Cleaned up the chassis ground behind the drivers side lights. Running lights and turn signal blinking works again. So glad the schematic was posted online. Made finding that ground a lot easier.

Wheeee32 for the win! Love it when the solution is essentially free.
