Can anyone help me, Recently on a ski trip, my brother who was driving ahead of me informed me that everytime I put on a front directional that sides daytime running light would go out. If the r/s directional is on, the r/s daytime running light goes out, and the same for the l/s. I asked my service advisor about this, and mentioned that other Acadia's I have seen do not have this problem. He stated that only Acadias with HID headlights do this. Has anyone with an Acadia with HID headlights checked this. Or is this a problem with my vehicle, and my service guy is just making excuses. Can anyone help. Thanks..... ???
