I assume you checked the bulbs and they were good? It's possible that the sockets have gone bad and need replacing. The tail lights are fused through the instrument panel lights. that fuse should be in the middle of your fuse box, marked "instr". If the fuse is good check to see if the dash lights come on when you turn the headlight switch on. If they don't then change the headlight switch. hope this helps.

The fuse block on all models is located under the left hand side of the instrument panel. All flashers are mounted on the fuse block. Each fuse is marked on the fuse block as to which circuit it is protecting. Some early models also use an in-line 30 amp, fuse for the air conditioning hi-blower, located at the cowl relay and an in-line 10 amp, fuse for power antennas.
