Guys I need help I have issue whit my G37.
My backup camera is not working the screen is all dark only the guide line appears. No backup light, no lights on the trunk, the trunk cannot be open. Any idea is it a fuse or a wire that is cut somewhere?

 

Since nothing in your trunk lid seems to be working, my guess is you lost the ground wire. Pull back the rubber boot that goes from the body to the lid and look for broken or frayed wires. That's the most likely spot.

 

Thanks I will try that
