good evening to everyone i got a problem with my lights my turn signal lights. every thing was working fine until i was gona tow a trailer with my bronco i plugged in the trailer to my seven blade trailer plug which i had installed at a shop tow years ago. so when i plug it in my turn signals don't work i un plugged it and still no turn signals my hazards work fine also my brake lights work fine just no turn signals. i changed to a heavy duty flasher just yesterday and still no signals the fuses are ok so that cant be it i don't know where to look any more? thanks for the help ahead of time .

 

What year bronco? You need to look at wiring diagram.

 

Knowing more about the truck helps , some broncos 1992-1996 have another fuse box under the hood . I do not know about the 80s to 91 models .TR

 

its a 1978 no fuse box under the hood only under the dash on the driver side.

 

Look at the back where the wires are and look for a blue wire. Thats the trailer light wire
