Front

1. With ignition switch in OFF position, unplug front washer pump wiring connector.
a. Measure resistance from terminal A of front pump connector to a good ground. Meter should read zero ohms. If not, repair wiring to ground.
2. Remove circuit breaker from fuse block and turn ignition switch to ACCESSORY or ON.
a. Measure voltage at battery side of circuit breaker cavity Meter should read battery voltage. If not, repair wiring from ignition switch.
b. Measure resistance across circuit breaker terminals. Meter should read zero ohms. If OK, reinstall circuit breaker. If not, replace failed circuit breaker.
3. Unplug wiring harness connector (multi-function switch side) from intermittent wiper module, and turn ignition switch to ACCESSORY or ON.
a. Measure voltage at unplugged connector terminal B while washer switch is depressed. Meter should read battery voltage If OK, reinstall connector. If not, repair wiring back to circuit breaker and/or refer to Multi-Function Switch Diagnosis.
4. Unplug wiring harness connector (washer pump side) from intermittent wiper module, and turn ignition switch to ACCESSORY or ON.
a. Measure voltage at unplugged connector terminal B while washer switch is depressed. Meter should read battery voltage. If OK, reinstall connector. If not, replace failed intermittent wiper module.

CAUTION: When replacing intermittent wiper module, be certain to use the correct replacement module. If an incorrect substitution is used, the wiper delay will be incorrect.

5. With ignition switch in ACCESSORY or ON, unplug connector at front washer pump.
a. Measure voltage at washer pump connector terminal A while washer switch is depressed. Meter should read battery voltage. If OK, replace failed front washer pump. If not, repair wiring from intermittent wiper module.
