All my lights work except my parking lights? When light switch is in either position parking or headlights they dont work. Turn signals, hazards and everything else works just fine. Checked all fuses and relays couldnt find any problems there. Suggestions plz.

 

What year is it?

 

2002 FX4 Screw.. 5.4l

 

That's fuse #6 under the hood I think. Try another fuse in case there's a break inside the fuse. I've seen that happen.

 

Tried a couple fuses. Still no luck. Any more ideas before she goes to the dealership?

 

even your tail lights or is it just the front to marker lights?if soo maybe a bad switch if just head lights are working...

 

Only the marker lights dont work. All other lights work on the truck. I was thinking of trying a switch before taking it in.

 

same happened to me today... i blew fuse #6

 

wish it was just a fuse for me..

 

Bad headlight switch was the culprit.. replace all is working again
