Question Side mirror blinker fix?
Hello all,

My side mirror blinkers aren't working anymore and I can't seem to find replacements for them anywhere. Does anyone know of a DIY fix, or am I pretty much stuck?

FYI: P/N is: 163-820-04-21

Thanks,

Remove relay K12 and replace it with similar relay on the board and see if the blinkers work.

I put the hazards on and checked the connection with a DIMM and it was getting proper voltage. That means the LEDs are shot, right?

Clearly a low fluid issue which can be resolved quite easily

I understand your suggestion, but didn't I already rule that out by finding voltage at the plugs the LEDs plug into, or am I missing something?

​​​​​​Not possible, I just flushed the entire system and filled it with two quarts of full synthetic blinker fluid.
