The other day i was changing my license plate lights and left my headlights on while changing them all of the sudden it sparked and my license plate lights wouldn't turn on again. None of my back night lights work (tail light + license plate light) but the tail light works when i press on it.
I have checked both fuse boxes and everything seems to be working. Any suggestions?

 

did you really have to put this in two places?!

 

check the fuses again?

 

You blew a fuse. Check harder.
