I need to find out where to check for fuse, module location before replacing tail light assembly. Any help on which fuse box, front, back, passenger front compartment would be helpful, plus which fuse? Module? Location to look at. Thanks

Hello, I am Danny.

I have attached a few pictures of your under hood fuse box including the fuse location for the right rear tail lamp. I have also attached a wiring diagram for you as well. I have also attached a tutorial showing how to check wiring. Hope this helps and thanks for using 2CarPros.

Can I test the wiring at the light with a volt meter and if so which is the ground and then the positives?

Hello again.

The ground is black wire and power is the green/white. Yes, you can test with a voltmeter. I have attached another tutorial showing how to use a voltmeter. Hope this helps and thanks again for using 2CarPros.
