yeah ... the car is less than 2 yerars old and has electrical problems......
That seems odd, could you explain why it is out of warranty ?
Unfortunately, you have to go with a process of elimination, and hope you hit the issue sooner rather than later.
Start with disconnecting the camera. If the fuse no longer blows, it is most likely a bad camera - the camera can be replaced. If the fuse still blows, it could be a bad connector. If replacing the connector does not fix the issue, then there is most likely an issue with the wiring itself (probably crimped somewhere?), and finding the issue could be a pain. Having an electrical wiring schema diagram (from Chevy's Service Manual) should help.
The sun visor lights are both connected to the same F7DR fuse.
Did a ground come lose somewhere? That can cause current to flow weird to find the ground.
I'ii check it.... is it the traditional 12.3v + good batt ????I wouldn't completely rule out the battery. There were a few instances of bad batteries that only lasted a year or so.
Try putting the car in Reverse, and moving the visor back and forth repeatedly. If the camera cuts out while you are doing that, then you may have found the issue.
