you prob need new bulbs
if only one turn signal is out your looking at a blown bulb not a fuse as the turn signals are on one fuse if it blew none of your signals would work but to check anyway look in manual to find which fuse is turn signal fuse located fuse box and pull it
In the fuse box. They are often labeled.
Bad flasher, fuse...
It depends on the vehicle but in general you would have one fuse for the signals and one fuse for the brake lights.
my turn signals do not work in my 1992 Pontiac Firebird
broken wire likely
Check the turn signal relay. The four way flasher and the turn signals each have their own relay. It has a fuse for the turn signal
Check your relay switches that should be located near the fuse box.
I asked my dealer the same question and he said there is no fuse for the turn signals. There is a flasher assembley. If you think you blew a fuse check the flasher assembley but where is that?
Flasher and fuse
Turn signal flasher module?
Check the fuse panel it is possible you blew the fuse needed to run the turn signals
