My radio and cigarette lighter dont work - 1992 Toyota Camry V6

Some radio power sources also tie into the cigarette lighter and power adapters. You mentioned fuses appear ok, if you dont have a test light to test both sides of the fuses try swapping the fuses around from another location and see if that changes anything.. Oh and if the penny is still in the lighter try a ball of tape of the end of a pencil to pull it out.. Look for a fuse listed aux. power or radio/cig lighter. Most likely the fuse is inside the car not under the hood..(usually)..

check fuse for cigarette lighter.

You should replace both your battery and cigarette lighter.

Check fuse 9 15amp ,this controls ciglighter/radio
Fuse box located glovebox area,check owner manual for location

Spin or replace the fuse as the old aluminum fuses build up corrosion and dont work, or work on and off.

If its an after market radio check by removing unit and checking for fuses in line.

Check the fuse box under the hood, one of them should be blown

Check behind the dash for loose wiring connections. Check for bulkhead connectors that could have possibly come partially apart. Check for any under dash grounds that are ready to break or have become frayed.

You can pull the fuses one at a time and look at them.You will know the bad fuse when you see it.

check the fuse for dome and the map light if applicable
