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?

 

"No lights on the trunk" do you mean no tail lights?

On the V35 platform it's fairly common for the wires to break inside the flexible conduit section, since you have multiple unrelated systems that are not functional I'd say the same probably happened to you.

Back seat should fold down similar to the V35, dig around where the back and seat sections meet right in the middle and look for a RED PULL CORD to fold the rear seatback down. This will allow you to access the trunk and pull the manual trunk release, then you can start testing for power.

Make sure you didn't accidentally turn off the trunk release button inside the glove box. However since you have other trunk stuff not working this probably isn't the case.

 

You will also probably have more luck posting this on MYG37.COM since this site is almost entirely for the V35 platform cars.

 

it’s the backup light thanks for your help
I will try to open the trunk to see.
