Hi ,
Hope someone can help I have 2020 Silverado custom , I installed roughly 2 years ago a opti 7 light bar. Fast forward to today its broke doesn't light correctly , bought a new one new one and it doesn't work properly. Left blinker on trailer plug is constant hot , trace to fuse 73 .
My question is what is powering fuse 73 is it the bcm , if it is do we think warranty would cover repair since the light bar is what messed it up or should I bypass the bcm for this pin and hard wire to the blinker its self.
