Wipers Start Erratically During Delay Mode

Intermittent wipe and standard two-speed motors are identical. Refer to TWO SPEED WIPER SYSTEM in this section for diagnosis of system problems not involving the delay function.

1. Verify that ground connection at instrument panel is tight and making good contact.
2. Verify that motor ground strap is making good contact and that motor mounting bolts are tight.
3. Verify that wiring ground connections for intermittent wipe control unit and wiper switch are tight.
4. If condition persists, replace control unit.
