Turn signals
Door lights.

Tail lights

Map light
Glove Box Lights




Solutions Attempted:

I checked all the fuses and they appear okay.





Any recommendations of what to check, next?

Check all tail lights for corrosion in light sockets and/or melting due to overheating. If the bulbs are difficult to remove it could indicate overheating.
