Need some help diagnosing this... My drivers side front signal does not work (most times) when I click it down. It does work when I use the lane change feature. Occasionally, after using the lane change feature, it will work until I turn it off. Next time, no worky. I've been able to reproduce this scenario many times. The rear always works. And I can hear the flasher clicking. Are there separate contacts for the front and rear? That might explain it, and I'll have to pull it apart, try cleaning the contacts, check for a lose wire, or replace the switch (if I can find one). FWIW, I tried spraying some electrical contact cleaner in there but no success.
