If your GMC Acadia has a backup camera that is not working, here are the most common causes and how to troubleshoot them. Backup Technology is wonderful (when it works). The Acadia is a rather large vehicle and the backup camera can make driving it a lot more convenient, not to mention safer.
Troubleshooting GMC Acadia Backup Camera Problems
This section is presented to you in the order of likelihood that the particular issue is causing the back up camera problem with your GMC Acadia.
Bad Shifter Alignment– This is a really easy one to check. Have somebody stand behind your Acadia, and put it in reverse. Have them tell you if the back up lights come on.

Go ahead and install a new fuse, and if the problem goes away you’re good to go. If the problem persists, then it’s time to look at the possibility that you have a short-circuit.

Short Circuit– While it’s not the most likely of causes, the a short-circuit can cause the reverse camera to stop functioning . Here’s a video on diagnosing a short.
