Dom emailed me and said it's a 1991 Corsica. Without looking up specific
information on this vehicle, I am guessing it has two flashers, like most
GMs, and you replaced the wrong one. If the signal light comes on but
doesn't flash when you flick the switch, then the switch is working. I am
99.99% sure your flasher is gone and you just replaced the wrong one.
If you have trouble finding the right one, I'm sure someone here can tell
you where it is, if not I will look it up tomorrow.
I finally figured it out. I posted to the following site below:
Remove the cover under the steering column, then remove the cover over the
Looking at the steering column, three inches directly to the left is a
bracket mounted vertically. On the other side of the bracket is a
'convenience center'. You can see the convenience center better by using a
mirror. On the convenience center are three items: 1) A brown component
which has a speaker which beeps when you don't fasten your seatbelt. 2) A
white relay for your horn. 3) On top of the white relay is the hazard lights
The signal light flasher is above the convenience center. Don't try looking
for it because you can't see it, even with a mirror. To get the signal
flasher out, look at the bracket located three inches to the left of the
steering column. One inch from the top of the bracket is a small square hole
about 3/8 inch square. Look closely and you'll see a clip is mounted in this
hole. This clip is holding the signal flasher, which is connected to two
wires. Wiggle this clip out of the hole with a screwdriver.
Once the clip is free, you should be able pull the two wires and the flasher
down and replace the flasher. Don't try to put the clip back into it's
original position - just tape it somewhere under the dash.
