Where is the turn signal flasher located on a 1987 cutlass supreme. I have no turn signals and have changed all the bulbs. Help!

On 1980 and later models, both the turn signal flasher and the hazard flasher are located at the lower left hand and the upper right hand corners of the fuse block respectively. Remove these by pulling them from their connectors.
The lower dash panel may have to be removed to gain access to the unit.

Flashers

The turn signal flasher is mounted in a clip on the right side of the steering column support bracket. The hazard flasher is located in the component center, under the instrument panel, on the right side. Replace the flasher by unplugging the old one and plugging in the new one.

most likely its your muti-funtion switch in the steering column.but first check your turn signal flasher & your emergency flasher

Try having someone push on brake pedal at the same time thay move the turn signal lever up and down slightly to see if your brake lights work this would tell me that you have a faulty turn signal switch because GM runs the brake lights thru the turn signal switch so they work if you are driving with your 4way flashers on.

You changed the hazard flasher or the turn signal flasher? It has two, one for the hazard and one for the turn signals

try checking if you got power going to the socket. It could also be the switch itself.

My turn signal flasher was located to the right of the ash tray, I looked around the column for HOURS and it wasn't there... I also have an 93 oldsmobile cutlass ciera, it drove me crazy because the manual wasn't correct.

under the dash on the driver side there is a round or square sliver box that should say turn signal or flasher on it in the fuse box.

There are two flasher units,one for the turn signals,and another for the emergency,or 4 way flashers.There is a possibility you replaced the wrong flasher unit..

when you turn on the blinkers do they stay a steady on?
if so then on bulb is not the right one or one is not working
