Hello all,

Ok I have a couple of things going on and not sure if they're related or not and wanted to get some ideas if anyone has seen this or your thoughts.

So for the longest time now (maybe a couple of years) whenever the left turn signal is engaged a chime will just start dinging and dinging non-stop until I put the multifunction stock back to center, OR, if I move the stock to engage the right turn signal, then immediately move it to the left turn signal the chiming will not occur at all. I checked both front and rear signal lamps blink for both left and right.

Now the main reason why I made this post. About a month ago out of the blue I lost the ability to use my high beams (sort of). What's happening is with DRL they work fine (outboard low beams come on) and when it gets dark outboard low beams come on (both sides) just fine. BUT if I go to push the multifunction stock forward to engage the high beams the only headlight that comes on is the inside driver's high beam headlight. The driver's side low beam doesn't come on, and neither of the passenger lights come on at all.

If I pull back on the multifunction stock to temporarily turn on the high beams what will happen is the driver's side high beam and passenger low beam lights will come on, but the driver's low beam and passenger's high beams won't come on at all. So it seems like the passenger side high beam doesn't come on at all no matter what I do.

I checked all of the fuses for the headlights inside the engine bay and they're all intact. So I don't know if its a burnt out bulb that needs to be replaced causing this or if its an issue with the multifunction switch but would like to see if anyone else has seen or dealt with this before.
