1. The Relay Itself:
* Visual Inspection: Check the relay for any obvious physical damage (burnt contacts, cracks, etc.).
* Clicking Sound: When you turn on the system the relay controls (headlights, wipers, etc.), do you hear a clicking sound? A single click usually means the relay is engaging but might be faulty. No click suggests it's not getting power.
* Replacement: The most common solution is to replace the relay. They're inexpensive and readily available at auto parts stores. Make sure you get the correct one for the specific circuit (e.g., headlight relay, fuel pump relay).
2. The Circuit:
* Power Supply: Verify power is getting to the relay. This requires testing the wires with a multimeter to ensure voltage is present when the system should be on.
* Ground Connection: A poor ground connection can also prevent a relay from working. Check the ground wire connected to the relay and ensure a good clean connection.
* Wiring: Inspect the wiring leading to and from the relay for any damage, shorts, or loose connections. A frayed wire can cause intermittent problems.
* Fuse: Check the fuse that protects the relay's circuit. A blown fuse indicates a problem elsewhere in the system, which needs fixing *before* replacing the relay.
3. The System the Relay Controls:
The problem might not be the relay itself, but the component it's controlling. For example, if the headlight relay isn't working, the problem could be a faulty headlight switch, a short in the headlight wiring, or even a blown headlight bulb.
How to Find the Right Relay and its Location:
1. Your Owner's Manual: Check your 1996 Dodge owner's manual. It should have a fuse and relay diagram showing their locations and what each one controls.
2. Online Resources: Search online for "[Your Dodge Model Year] relay diagram" or "[Your Dodge Model Year] fuse box diagram." Many websites and forums have this information.
3. Auto Parts Store: Auto parts store employees can usually help you identify the correct relay for your vehicle and its location.
Important Note: Working with car electrical systems involves working with potentially high voltages. If you're not comfortable working with electricity, it's best to take your vehicle to a qualified mechanic. Improper troubleshooting can lead to further damage or injury.
