Brake lights work but the tail lights and tag light does not work when I have the lights on. What is the issue?
I have a 2004 Ford Crown Victoria. The tail lights and tag light do not work when I have
the lights on but the brake lights work. Is it a fuse? Is it a relay?
check fuse,s and ground wires
Which fuse and where is it located
It might actually be inside of the lighting control module. This was problem on many of the cars. When my LCM burned out on one of our Mercurys, we had front signal lights but no headlights. These modules were a problem in their first years of use. as all lighting goes through them. It could also be in the dash switch.
