Rear Cameras Dark At all times

[Byrds8]

Since I purchased my truck in October, the rear camera has always been darker compared to all of the cameras on the truck. I took it to the dealership and they replaced the backup camera, however, it did not fix the issue. When I showed the SA it wasnt fixed, we looked at the trailer hit camera and it was dark also. He said he had to open a case with GM to try and figure it out. My question is, if anyone knows, what is the common connection for both cameras. I assume they both connect to a central point somewhere and maybe that is the issue since it doesnt appear to be the camera itself.

 

Thanks

Byrds,

My 26 3500HD LTZ is the same.

I’m not sure I understand which cameras you are asking about, but the rear backup camera and hitch view camera are one wide angle camera at the tailgate handle. The system just gives different views from that one camera for back up and hitch view.  That may be why the two views you are asking about have similar lack of brightness.

I thought that there were two different modules there, one for the standard back up and one for the hitch. Well then, maybe the new module sucks or they didnt actually change it.

That sucks. That's also weird considering every other vehicle I have owned with this, all cameras looked the same. You can even see the shading of the rear camera from the "overhead" view too.

I should have stated that I was describing the way my 2021 truck rear camera is configured. I don’t know of they changed it for your year.
