Fig 9 Front Intermittent Wiper/Washer Circuit Diagram:





1. Remove circuit breaker from fuse block module and turn ignition switch to, Accessory or On position.
a. Measure voltage at battery side of circuit breaker cavity. If battery voltage is not indicated, repair wiring from ignition switch.
b. Measure resistance across circuit breaker terminals. If meter does not read 0 ohms, replace circuit breaker.
2. On models with standard wipers, unplug wiper motor side of wiring harness gray connector from wiper switch side of wiring harness black connector.
3. On models with intermittent wipers, unplug wiper motor side of wiring harness gray connector from intermittent wipe module, at base of steering column.
4. On all models, turn ignition switch to Accessory or On position.
a. Measure voltage at unplugged wiper motor side of wiring harness gray connector terminal D. If battery voltage is not indicated, repair wiring from circuit breaker.
b. Turn ignition switch Off and measure resistance from unplugged wiper motor side of wiring harness gray connector terminal G to ground. If meter does not read 0 ohms, repair wiring to ground.
5. Leave ignition switch Off and backprobe wiring harness connector at motor. Measure resistance from terminal E to ground. If meter does not read 0 ohms, repair wiring to ground.
6. On models with intermittent wipers, turn ignition switch to Accessory or On and turn wiper switch to Low or High. Unplug wiper switch side of wiring harness black connector form intermittent wipe module. Then plug both connectors that have been removed from intermittent wipe module into each other. Do not move the wiper switch to Delay with the intermittent wipe module removed from the circuit during the following procedure step as the switch will be damaged.
7. Test wiper operation in Low and High speed modes. If these modes were inoperative, but now are functioning, replace intermittent wipe module.
