I'm looking for help identifying the right part number for my rear view mirror. It has autodimming, compass, automatic headlights, and rain sensing wipers. There is something wrong with the wiring inside. Adjusting the mirror, or even a rough bump in the road can make the the headlights go off (only in the automatic setting). Wiggle the mirror and the lights come back on. I went to the parts department of the nearest dealer and using the VIN, they gave me a choice of two parts:
HJA3121BA which has a white plug with 4 wires, or
HNC3133AB which has a yellow plug with 6 wires.
My mirror has a black plug with 5 wires. Poking around on the internet I came up with a part # C2P1823, which looked like it might be right from the pictures.
Has anyone had experience with this? Before I order a super pricey mirror, I want to be sure of getting the right one
