You have to remove the entire fuse box. It's bolted in from the bottom.
Visually it looks good through the clear plastic window. Is there a way to test it without removing the entire thing? Just apply the positive and negative probes to either side of the fuse?

I don’t think you can isolate it that way.

Getting access to that fuse box is like a puzzle. You will need 4 long zip ties to unhook 4 holding tabs. I can post pictures when I get home of what I am talking about.
