Code B3703 Description
The B3703 diagnostic trouble code (DTC) indicates an issue with the intermittent wiper delay input circuit being too high. This code typically relates to a problem in the electrical system that controls the intermittent wiper function in a vehicle. The intermittent wiper delay input circuit is responsible for adjusting the delay time between each wiper sweep, allowing the wipers to pause briefly before continuing to wipe the windshield.
Common Causes of B3703
- Faulty intermittent wiper switch
- Damaged or corroded wiring connections
- Defective wiper control module
- Malfunctioning wiper motor
- Water infiltration causing electrical issues
Symptoms of B3703
- Wipers not pausing at set intervals
- Wipers operating at a constant speed without delay
- Wipers not working at all in intermittent mode
- Unusual or erratic wiper behavior
How to Fix B3703
- Begin by performing a thorough inspection of the intermittent wiper system, including the switch, wiring, connectors, control module, and motor.
- Test the intermittent wiper switch using a multimeter to check for proper functionality and continuity.
- Inspect the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
- Test the wiper control module and motor to ensure they are operating within specifications. Replace any components that are found to be defective.
- Clear the DTC from the vehicle's memory using a diagnostic scan tool after completing the repairs and test the wiper system to verify that the issue has been resolved.
