* Under the hood, in the fuse box: Many Dodge vehicles from this era housed relays within the main fuse block or relay panel under the hood. Check the fuse box cover – there's often a diagram showing the location of relays.
* Under the dash: Less common, but some relays, especially those for less frequently used circuits, might be located in a secondary relay center under the dashboard.
* On the firewall: Relays sometimes mount directly to the firewall, often near the battery's positive cable or the starter motor itself.
To find it:
1. Consult your owner's manual: The best place to start is your vehicle's owner's manual. It should have a diagram showing the location of all fuses and relays.
2. Locate the fuse box: Open the hood and look for the main fuse box. It's usually a plastic box with numerous fuses and possibly relays.
3. Check for labels: The relays often have labels indicating their function. Look for one labeled "starter," "start," or similar.
4. Trace the starter wire: If you can't locate a labeled relay, follow the heavy-gauge cable running from the battery to the starter motor. The relay should be in the path of this wire. This is more challenging but sometimes necessary.
5. Use a wiring diagram: A wiring diagram specific to your 1987 Dodge van model is your best resource if the above steps fail. You can often find these online via sites specializing in automotive repair manuals.
If you're unsure about working with electrical components, it's best to consult a qualified mechanic to avoid potential damage to your vehicle.
