I have the weirdest thing going on. I’ll open the ignition (before starting) and I’ll turn on my signal light (right) and the blinker will work just fine. I’ll then turn on the car and the signal will keep working for about a minute or so. I’ll then get an error message in my cluster to check the bulb and the blinker will stop working. I haven’t been able to locate the fuse or the relay as the manual does not state any of that info. Any help would be great! Thanks

Anyone know what fuse controls the sign light?
