Intermittent Circuit Time Cannot be Adjusted
- Check intermittent wiper volume circuit. Turn ignition switch to "OFF" position. Measure resistance between terminals No. 2 (-) and 16 (+), while turning intermittent wiper volume knob. Ohmmeter should read zero ohms at position "S" and one ohm at position "L".
- If intermittent wiper volume control circuit is okay, check intermittent wiper volume. If volume is okay, check harness between time control unit and intermittent wiper volume. If intermittent wiper volume is not okay, replace the wiper switch.
