First check all your fuses.

If all fuses are good, you may have a wiring problem. If you are mechanically inclined, will need to remove the required components to expose wiring and see if you have a break somewhere. Most wiring harnesses run along inside of vehicle trunk. Then, they continue under rear seats and possibly under carpeting.

It is the same fuse as the courtesy lights and cigarette lighter. It may be in the interior fusebox or the exterior one.

I don't see a power connection to the three components. The interior lights are on a 20 amp courtesy fuse, the cig lighter should be on a 30 amp ACC fuse, and the mirrors are probably powered thru the key on a different 30 amp ACC fuse.
The only common factor would be a ground connector somewhere.
If they all died at the same time, a ground problem would be my guess.

{: ) There are two fuses that protect the front IP power outlet or lighter plugs. At the underhood fuse block, labeled CIG LTR 15amps and AUX PWR 20amps. See red arrows on diagram below.
The fuse on the driver side door fuse block labeled AUX PWR2 20amps protects the rear lighter plugs.

check fuse for dome and cig. lighter

These items clock, radio, dash lights are usually fused on the same circuit. Please check the fuses for this problem. The fuse or fuses should be listed on the fuse box cover inside the interior fuse box. Replace the blown fuse if that is that problem. If it blows again, then the cig lighter circuit may be involved. Make sure the cig lighter is free of any objects, remove lighter, (push in part). Try new fuse while lighter is out, and if problem goes away, push in may be bad.

two relays were bad one for the interior light and cig lighter and the other for the headlights
