I have just noticed neither of my indicators are working. I've tried to do things that will cause the sensors to work but I haven't been able to get them to react. I do still get a beeping at the bottom of my driveway as I'm pulling out but no mirror indicators. I looked up the fuse but there are a couple of other things tied to that fuse and they are working. I haven't taken it in yet but there is nothing showing me there is an issue other than the indicators not working. Any idea what this could be?
