Bought towing mirrors for my 2017 1500 Silverado LT. Went and installed my mirrors. Everything worked good for the first week. followed the wiring shown above for my turn, running, and cargo lights. On my way back home from vacation, my DIS told me my turn signals were not working , this was intermitted. Now that I am home after my trip of towing my trailer, when my lights come on so do my turn signal on the mirror and the front markers continually blink. Was thinking about disconnecting the markers and just using the turn signals. Any help would be grateful.
