Replace the flasher unit. If it doesn't help it is probably the turn signal sw. They are a medium failure item and dealer only for about $50.00

Suggested Repair

Replace the flasher unit. If the turn signals still do not work, the turn signal switch is the likely cause and is typically a dealer-only part.

All three flasher fuses and the regular fuses were checked and found fine. The expert advised replacing the flasher unit, and if that does not help, replacing the turn signal switch.
