NOTE:
Same test procedure may be used for all wiper/washer system relays.
- Remove relay. Measure resistance between terminal No. 2 and all other terminals. See Fig 1 . If resistance is 5 ohms or less between terminal No. 2 and any other terminal, replace relay. If all resistances are greater than 5 ohms, go to next step.
- Using 2 jumper wires, connect terminals No. 1 and 3 to battery positive terminal. See Fig 1 . Connect voltmeter negative lead to battery negative terminal. With remaining voltmeter lead, check for voltage at terminal No. 4. If battery voltage exists, go to next step. If battery voltage does not exist, replace relay.
- Connect another jumper wire between relay terminal No. 2 and battery negative terminal. See Fig 1 . Check for battery voltage at relay terminal No. 5. If battery voltage does not exist, replace relay. If battery voltage exists, relay is good.
