Tail light short
 

New to this site. Looking for some assistance with a problem with my 2015 Silverado LTZ
Had to put a new rear bumper on (did it myself) in doing so I pinched the harness going to the left rear tail light assy.
Started seeing "left rear turn indicator failure" on dash. That's when I found the pinched harness. Fixed harness checked bulbs /replaced bulbs just to be safe, still have the message. My code reader shows no DTCs
Cant find any fuses for this area.
Can I safely disconnect the positive to reset the system?

Dear Mr. GeoS54,
The tail lights that were made for 2015 Chevy Silverado where made cheap it didn’t short it burnt up the socket for the light bulb. You can get another oem replacement harness @carid.com
