no tail lights

^^Yup. You cannot just go by "looks"^^ The tail fuse should be hot whether key is on or not to test get your test lamp or a meter. Turn on the headlights. This is to put a load on the circuit. Make sure the test lamp is grounded and probe BOTH ends of the tail fuse. Both should be hot

Several things can go wrong there.........

Clips can be loose from heat / corrosion damage.

Clips can be rusted / corroded, losing contact

Fuses sometimes blow in the end caps where you cannot see. This is usually also caused by a poor connection at the clips, because that generates HEAT

Last, might be poor connections between clips and buss/ wire connections in the back of the fuse panel.

If that looks good get into the left kick panel. There's a connector in there where the rear harness takes off to the rear of the car. As above ^^ get into the diagram, find the wire color, and probe for power. There is only one wire supplying tail lamps and if equipped on newer cars, side marker and license plate lamp

THAT ALSO can be a clue. If you have markers and they work, or the license plate lamp works, but not tail lights, RIGHT AWAY you should realize that power is "making it" to the rear, and the trouble HAS to be in the sockets or bulbs.

You do realize? I hope? that tail /stop bulbs are actually two bulbs in one. IE the tail section can burn out but the stop / turn filament can still work.
