How to Replace an Integrated Power Module Relay in a Dodge Caravan
by Editorial TeamThe Integrated Power Module (IPM), located in the engine compartment of your 2004 Dodge Caravan, houses the fuses and relays that help regulate your vehicle's electrical system. Relays specifically help with regulating the flow of high current to and from certain devices or systems. If one of these high current devices or systems malfunction or stop working, you may have a loose or damaged relay, which you can easily replace.
Step 1
Confirm the type of relay you need to replace in your 2004 Dodge Caravan. Determine the location of the relay associated to your malfunctioning device by referring to the diagram/relay key under the latching cover of the IPM (located to the right of the battery).
Step 2
Disconnect the battery. Remove the relay. Clean and fix or repair any area of the relay or IPM, as needed.
Step 3
Push your new replacement relay into the relay socket. Make certain the relay fits snug within the socket, as current running through a loose relay can cause the relay to overheat and the outer relay casing or IPM cover to melt.
Step 4
Snap the IPM cover tightly in to place. A loose IPM cover can allow moisture or water into the IPM resulting in damage and high cost repairs due to electrical system failure.
Step 5
Reconnect the battery and reset the clock and any radio presets. Verify that the new relay corrected your Dodge Caravan device or system malfunction.
Tips
- Consider resoldering your old relay's joints to restore it to working condition. Soldered joints on a relay's circuit board can suffer microscopic cracks that cause resistance and a voltage drop. Inspect the circuit board with a magnifying glass to discover these cracks and repair, as needed.
Things You'll Need
- Replacement relay
- Magnifying glass (optional)
- Soldering tools (optional)
