Fuse is good, but lights don't work. Left or right turn signal or brake lights won't light.

Hello,

This is common when the turn signal switch goes out but to be sure here is the blinker wiring diagrams and a guide to help check for power at the turn and hazard fuses at the dash fuse panel and under the hood. The wiring diagrams shows you the fuses you should check.

Check out the diagrams (below). Please let us know what you find.
