Lost lights on dash and tail lights but fuses are good

Check power in and out of dimmer switch.

What about the fuse box inside the truck? You did blow a fuse that I am sure of.

THE TAIL/MARKER LIGHTS, GO FROM THE HEADLIGHT SWITCH TO THE REAR FOR THE TAIL LIGHTS & TO THE FRONT FOR PARKING OR RUNNING LIGHTS. ALL THOSE LIGHTS ARE ON THE SAME CIRCUIT, { BROWN WIRE } THE BRAKE & TURN SIGNAL WIRES GO FROM THE STOP LIGHT SWITCH & FROM THE TURN SIGNAL/HAZARD SWITCH. NO RELAY IN THE TAIL/PARK CIRCUIT. CHECK THE FUSES WITH A GOOD FUSE TESTER.

They should all be on the same circuit so I' check the fuses 1st.

Look at fuse #18, a 15 amp fuse, in the fuse block. This fuse powers both the tail lights and instrument cluster lights. Usually both of these light systems are powered by the same fuse so when your cluster isn't lit up you'll know right away that your tail lights aren't working as it's not safe to drive without tail lights. Your brake, turn, and head lamps are powered by different circuits. Hope this helps and good luck!

I have a f-250 super duty,2001, dash& running lights don,t work, found a 15 amp fuse blown in engine compartment. fuse,s keep blowing. please help.

headlight switch bad,possibly a bad dimmer switch they do short out in time

probab;y a faulty ground problem.

The fuse should be under the dash on the fuse panel. Look again!

Check fuse NO.11(7.5amp) in the under dash fuse panel.
