No dash/tail lights

I have a 2002 Alero.
Dashlights and Tail lights are not working. Service vehicle light is on. Both dash and tail lights have worked briefly after not working.
It is not a fuse.

Anyone have similar problem or know what might be the problem?

Thanks!

Check are any wire crimping in the rear lights.

I will check.

Are you referring to where the wires come into the actual taillight assembly and/or would you peel back the wire cover and trace back?

Thanks!

Right behind the light assembley.

It was the parking lamp relay.
