Good morning,

Parts stores employ sales people. They are guessing as usual and need to sell you something.

There is a lot involved in the back up light circuit. I attached a picture of the location for you as well as a wire diagram with the fuse location.

I would start by doing testing on the circuit before throwing parts at it.

I attached a wire diagram for you for the rear back up lights. You will need a scan tool that can read the BCM as that is what sends out the power to the lights.

Test the fuses for power on both sides.

What is the ECAS you are referring to?

The fuse is for the auto level control system compressor.

Disconnect the compressor and see if the fuse still fails.

Okay, I attached a diagram for you for the back up lights a while back. It shows a light blue wire for the back up lights.

Attached is the diagram for the other lights.
