you need to replace the bliker can in the fuse box.
Thre is no fuse but a relay on the fuse panel, under the driver side dash. The round metal can is what you want to replace.
The fuse for the dashboard is located in slot 18. The fuse for the blinkers is located in slot 3.
I am currently having the same problem you are having check the fuse to see if it is blown the blinkers and brake lights are on the same fuse my system has a short in it somewhere and is popping the fuses I am in the process of running new wires since the wonderful people at Chevy ran all the wires thru the frame and you can't access them
*you might have a problem in the steering column *you may need to replace the flasher fuse in your fuse box.
Check the Fuse.
WHAT YEAR ?????
In a 1995 Oldsmobile Achieva, the fuse for the blinkers is located in the fuse box, which is typically found under the dash on the driver's side. You can identify the specific fuse for the turn signals by consulting the diagram on the fuse box cover or referring to the owner's manual. Look for a fuse labeled "Turn Signal" or "Blinker." If the fuse is blown, replacing it should resolve any issues with the blinkers.
The fuse for the blinkers on 2000 oldsmobile alero is in the driver's side fuse box, on the left side of the dash. It will be labelled TURN LPS, just remove the whole panel and you will find the fuse.
There isn't a separate fuse for the blinkers... they share a fuse with other lights. If no other lights are out, then you're looking at a different problem... might be a bad switch, might be faulty wiring.
It may be a bad fuse.... Try that.
If you check the fuse circuit box, there is a fuse for your blinkers. Just change to the amp that is required which is probably a 20. Should work good as new again
