my tail lights and dash lights do not work fuse is good what is the problem?

Hello, You likely have a bad headlight switch, as the dimmer switch for the dash lighting is integrated into the headlight switch. Before replacing, you should test the switch to see if it is receiving and sending power. If it is receiving power, but not sending power when the switch is turned on, it is bad. Also, it may have become unplugged after 25 years of jiggling around and hitting bumps.
