Service bulletin PI1187

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

PI-1255F2021-04-16. Service bulletin. Changing to Camper Outside Rearview Mirrors Some customers may request to have camper style mirrors installed on their vehicle. The new electrical architecture for the Silverado and Sierra has made swapping mirrors a more involved procedure than with previous models. The recommendation has been divided into three upgrades, depending on which mirrors the truck was built with (RPO DE2, DL8 or DL3). Please follow the correct RPO group below, because not all camper mirrors can be installed on all trucks. After selecting the correct RPO mirror the truck was built with, this PI will aid in determining which camper mirrors can be installed.
