My parking lights fuse keeps blowing any ideas? wiring looks fine, its a new switch but can that be why? i have turn signals, headlights, hazzards, break lights but it only seems to be the parking light just blowing them. as soon as i turn on the parking lights POP but headlights are still on.
Help?? i went through to many fuses lol tia

Remove each of the 4 bulbs For your parking lights run a ohm test on each socket .. With your meter put the black lead to a good ground , then with the red lead you put to socket power wire . If it ohms out u have either a bad socket or a wire that is sorting out to ground ,
