Steering column
The turn signal flasher on a 1975 Oldsmobile Delta 88 is located in the steering column. There is a small door panel on the underside of the steering column that is held on by clips. Both the turn signal flasher and the hazard flasher are located here.
Located on the driver side dashboard. Two metal cylindrical plugin units located deep under the dash above the steering column. One for the emergency flasher and the other for turn signals. If the emergency flasher works, it's the other one that doesn't click with the flasher turned on. If the E-flasher doesn't work, check fuses.
Probably the signal flasher relay, but be sure all the bulbs are okay.
On my 1993 Oldsmobile 88, it is number "8"
