Where is the ASD Relay on a 1991 Caravan 3 liter?

The ASD (Automatic Shut Down) relay location on a 1991 Dodge Caravan with a 3.0L engine isn't standardized in the way some components are. There's no single, universally agreed upon spot. It's often found in one of these areas, but you'll need to check your specific vehicle:

* Under the hood, in the power distribution center (PDC) or fuse box: This is the most common location. The PDC is usually a large plastic box located near the battery or firewall. The relay itself will be labeled, or you can use a wiring diagram to trace the ASD relay circuit.

* Under the dash: Less common, but possible. Look for fuse boxes or relay panels under the dashboard.

To find it, you'll need:

1. Your owner's manual: It might have a fuse box diagram showing the relay locations.

2. A wiring diagram: A wiring diagram specific to your 1991 Dodge Caravan 3.0L is essential. You can usually find these online through repair manual websites (like Chilton or Haynes) or forums dedicated to Dodge Caravans. The diagram will show you the ASD relay's circuit path and its likely location.

3. A multimeter (optional but helpful): This allows you to test for power and continuity to identify the ASD relay based on the wiring diagram.

Important Note: Working with car electrical systems can be risky. If you're not comfortable working with electricity, it's best to take your vehicle to a qualified mechanic. Incorrectly working with the electrical system can lead to damage to your vehicle or personal injury.
