Wiper Relay: Testing and Inspection

^ Using the multimeter, check for continuity between terminal 1 and all other terminals.
- If the resistance is 5 ohms or less between terminals 1 and any other terminal, install a new relay.
- If the resistance is greater than 5 ohms, continue with the test.
^ Using two jumper wires, connect relay terminals 2 and 3 directly to the positive battery terminal.
^ Using the multimeter set in the volts position, check for voltage at terminal 4.
- If battery voltage is not indicated, install a new relay.
- If battery voltage is indicated, connect a third jumper wire to terminal 1 and ground the jumper wire to a known good ground. The relay must click audible.







Check for voltage at terminal 5.
^ If battery voltage is not indicated, install a new relay.
