Hello,

Are you experiencing any specific issues?
One thing to keep in mind, if you are unable to find a good ground, you won't be able to test the fuses. Try a different spot for ground or maybe the same spot that you used to test the under-hood fuses.

Here is a helpful guide:

Let me know what you find or if you have any questions.
Thank you.

Thank you for responding so quickly.
I am having an issue with the radio, windows, dashboard, brake lights, as well as the shifter not being able to move out of park unless i press the button to the side with a screwdriver. I think it's related to the fuse box inside.
I had a family mechanic check it yesterday and he had the same ground when he checked the front fuses which were able to be read and had the same issue with the inside fuses not being able to read.

Have you pulled out the fuses to see if they are blown?

Also not being able to shift out of park could be due to a faulty shift interlock solenoid, which removes the lock when the brake pedal gets depressed. Also could be due to not getting power to the solenoid due to bad fuse.

I have, they aren't blown. All of them in the inside fuse box can't be read but they're not blown, is there a fuse that brings power to the inside fuse box?
Or a main fuse that powers the fuses inside.
Okay great, that's good to note.

It is possible to have a short in the main harness for the fuse box.
Check for continuity on the harness for the fuse box. Take a look at the diagrams below for the harness location.
