Do you have license plate lights when lights are on? If no check 15A Tail fuse. It supplies several dash lights and heater controls

Visible inspection of fuses is nice for a quick look type of check, but the only way to be sure if a fuse is good or not is to either ohm it out with a reliable multimeter, or replace it with a known good fuse. If you replace it with a known good fuse, like a new one out of the package it came in, and the problem clears, problem solved. If the problem still exists, it's after the fuse.

Personally, I go with the multimeter method. To my thinking, it's the ONLY reliable way to check a fuse. Pull the fuse out, touch the leads to each of the legs. Quick, easy, painless, and 100% accurate. A visual check can miss very small cracks or breaks in the fuse metal. Easily. Better to use a meter to verify that the metal strip in the plastic piece is electrically contiguous. No way fo doubt to enter your mind if you use a meter.

Just my opinion.
