LESS INTERMITTENT WIPERS
1. Measure resistance from washer pump connector terminal B to a clean chassis ground. If meter does not read 0 ohms, repair open between terminal B and ground.
2. Turn ignition switch to On and press washer switch.
a. Measure voltage at switch terminal B. If meter does not indicate battery voltage, replace wiper/washer switch.
b. Measure voltage at washer pump connector terminal A. If meter does not indicate battery voltage, repair open between switch connector and pump connector.

WITH INTERMITTENT WIPERS
1. Measure resistance from washer pump connector terminal B to a clean chassis ground. If meter does not read 0 ohms, repair open between terminal B and ground.
2. Turn ignition switch to On and press washer switch.
a. Measure voltage at wiper/washer switch connector terminal B located at intermittent wipe module. If meter does not indicate battery voltage, replace wiper switch.
b. Measure voltage at intermittent wipe module connector terminal B. If meter does not indicate battery voltage, replace intermittent wipe module.
c. Measure voltage at washer pump connector terminal A. If meter does not indicate battery voltage, repair open from intermittent wipe module connector terminal B.
