I recently bought a 94 5.0 when I bought it the blinkers and tail lights didn’t work but the break lights do work I’ve sorted through the fuses that could be blown and they were all fine. I’m not really that great when it comes to electrical problems what else could be the problem ?

 

I had a caddy one time the turn signal bulbs were blown. I am sure you checked them already but if you didn't

 

If you have a meter you could check the actual connection to see if the pins are corroded. Also check your blinker switch...they tend to go bad.

 

Awhile back, for my sons first car, We got a '98 Mustang, and the signals didn't work. It was very simple to crack the steering column, and change out the turn signal module...worked for us.
