Why might turn signals on a Buick not work?

If the turn signal does not work at all, the first thing to check is the fuse. either test the fuse with an ohm meter to verify that the circuit is complete, or replace it with a fuse you know is working. The amperage (number on the fuse) should be the same. If that doews not cure the problem, you should make sure the flasher is good. Often they are not too expensive and can just be changed. If this still does not work, user a test light to verify that there is power to the fuse, and then the light socket can be tested. It is rare that all the turn signal lights would be burned out. If there is light, but not flashing, on most general motors cars, the light will not flash if there is a bulb burnt out, so locate the burned out bulb and replace it. Another problem that exists in older vehicles is the loss of one or more critical grounds. Cleaning the sockets and measuring the resistance to ground will give you an ideal of what is going on there. If both elements light up (runnig and brake) at the same time then you may have lost the ground and the light is finding ground through another bulb some place. If some one has replaced the six volt flasher with at 12 volt unit you will have a steady turn lamp that will not blink.

If the turn signals in the dash don't work, what about the outside front and rear turn signals? Working? Not working? If it's not working, replace the turn signal relay under the dash.

I had the same problem with my 87 Riv. It was a burnt out bulb in the rear of the car. My front signals did work and as they run on different circuits, check and replace the bulbs. Access to the back lights are inside the trunk back.
