I recently towed a trailer. Everything worked fine. Drove vehicle next day and both turn signals stopped working. I looked for turn signal fuse. According to the legend on back of fuse box cover, no turn signal fuse exists. I checked ALL fuses - none are defective. I turned on emergency flashers which work fine. I located emergency flasher and discovered it is a combination flasher (hazard and turn). Internally, can a flasher work hazards, but be defective for turn signals? We also checked brake lamps since I believe they are associated with turn signal filament in the 3057 bulb, both worked fine. Trouble shot fuse, flasher, and bulbs, flasher seems to be the only thing that makes sense. ??Turn signal lever/harness in steering column?? Female desperately needs solution. Thanks for your help.

I have brake lights and emergency flashers work but turn signals don't. I have power to the flasher but when I turn on the signal it dies.
