Look along the steering column under the dash, sometimes toward the left side. If one side works, turn it on and follow the clicks. Mark
Flasher relay.
The trunk
Is the signal flasher underneath the steering wheel or somewhere else
I have a 93 and the signal relay is on the passenger side beneath the glove box. You can reach it by pulling the plastic panel out so that you can see and replace the flasher.
Trun signal lights do not come on at all not on dash or outside
FRONT SEATING AREA, DRIVER SIDE, UNDER DASH, ABOVE STEERING COLUMN, MOUNTED ON SUPPORT BRACKET
The turn signal flasher is located under the left hand of the instrument panel, right of the steering column.

I had the same problem with my 98 buick regal gs and it turned out to be the ignition switch.
I just did my Mom's 1991 Buick regal 3.8L. I removed the kick panel underneath the dash above the brake pedal. Follow the brake pedal arm up on the right side of the pedal. I used a mirror to spot the flasher unit. The flasher unit is held by a spring clip with the top of the unit pointing down. Just pull the flasher out of the clip and pull it down.
Bulbs or turn signal flasher, maybe even the switch.
