The best way to find it is to:
1. Consult your owner's manual: This is the most reliable source.
2. Look around the fuse box area: This is the most likely location.
3. Search online for a 1996 Chevy S10 fuse box diagram: This will often show the flasher relay's position within the fuse box or very close by.
Keep in mind that some models may have the flasher integrated into a larger control module, making identification more challenging. If you can't locate it easily, taking a picture of your fuse box area and searching online using that image might help.
