I have the weirdest thing going on. I値l open the ignition (before starting) and I値l turn on my signal light (right) and the blinker will work just fine. I値l then turn on the car and the signal will keep working for about a minute or so. I値l then get an error message in my cluster to check the bulb and the blinker will stop working. I haven稚 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?
