To find it, you'll need to:
1. Locate the underhood fuse block: This is usually a rectangular box, often near the battery.
2. Consult your owner's manual: The best way to find the correct relay is by using your vehicle's owner's manual. It will have a diagram showing the fuse and relay locations and their designations.
3. Use a wiring diagram: If you don't have the owner's manual, you can find a wiring diagram online (many are available through repair manuals sites, some free, others paid). The diagram will show the correct relay and its location within the fuse box.
4. Check online forums: Searching online forums specific to the 1995 Chevy S10 may reveal tips and pictures from other owners who've located the relay.
Without a diagram, it's difficult to give a precise location within the fuse box. The relay itself might be slightly different in size than other relays in the box, but visually identifying it based on looks alone isn't reliable. Using a wiring diagram or your owner's manual is the only foolproof method.
