Attention: Any changes or modifications to the vehicle should be first reviewed with the
customer, and then noted on the repair order with customer approval. This is for
customer satisfaction; this is not a warranty procedure. This bulletin also applies to
any of the above models that may also be export vehicles.
This PI has been revised to update the Models and Recommendation/Instructions.
Please discard PI1255.
Condition/Concern
Some customers may request to have a different style mirror installed on their vehicle or request a different mirror
before they purchase the vehicle. The new electrical architecture for the Silverado and Sierra has made swapping
mirrors a more involved procedure than with previous models.

indicators and puddle lamps (includes driver's side spotter mirror)

When swapping to the trailer Tow Mirrors, the first thing to know is the installation of the trailer Tow mirrors may
require the technician to add an additional mounting hole to the door (See chart below). Non-trailing mirrors only
require 3 mounting holes. Trailer tow mirrors require 4 mounting holes.
Secondly, the Side Mirror Switch may need to be replaced for trucks built with RPO DL3. See chart below:
