Trying to figure out where I am losing voltage for rear right blinker on a C3 II.
Connectors on the light module are OK, I tried on the left side, compared with a multimeter and I should get a pulsing Voltage (12V if I recall) but the gray one stays at 0 on the right side.
So I followed the wire all the way to under the glove box where I found what looks like a burned resistor.
Edit: it’s a plastic shielding:
I’m pretty new to this so if I’m looking at the wrong things please feel free to tell.
The waterproofing schmoo makes me think it’s factory. If you’re getting 0v at the rear connector there’s a break in the line somewhere. You’ll have to measure voltage along the wire to see where it drops. You can test the ground by checking for continuity between the negative connector and the body/frame.
