I need help before the cops pull me over for it. my turn signal stop working. one day it was flashing veryfast then it stop working. it will flash when i put the emergense light on but not the signal. it is a 87 formula 350. thanks

 

Replace the flashing unit under the dash. Cost a couple of dollars at the parts store, they will know what you need.

 

i but a new flasher in but nothing happend. the hazerd lights do still flash. put the turn signal do not. Anyone.

 

i was reading the chilton book and 82-84 it shows the flasher unit. But for 87-89 it will not show it.

 

I had a similar problem- left turn signal would not work, hazards operated fine (separate circuit) so it wasn't the bulbs. Replaced the flasher unit but no go. Turned out to be a bad headlight ground. I just cleaned them up and everything worked again.
