Wiper Circuit Open Code
Indicates an open circuit in the windshield wiper control system.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer is getting a signal that says the wipers should work, but when it checks, it finds no power coming through the wires where it expects it.
What the computer is actually seeing
The body control module (BCM) tries to activate the windshield wiper system and looks for a voltage change (typically around 12V) at the wiper motor, but sees no response.
What a healthy reading looks like
12V at the wiper motor terminals when the wipers are activated; resistance should be below 5 ohms in the wiring.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the wiper motor connector for corrosion or loose connections.
- 2Inspect wiring between the BCM and the wiper motor for damage or shorts; repair as needed.
- 3Measure voltage at the wiper motor connector when wipers are activated; expect 12V. If no voltage, proceed to step 4.
- 4Check BCM output signals with a scan tool; if the BCM is not sending signal, may need replacement or recalibration.
- 5If voltage is present but motor does not work, replace the wiper motor.
Common causes
- Damaged wiring or connectors in the wiper system
- Faulty wiper motor
- Bad body control module (BCM)

Frequently asked questions
Is it safe to drive with this code active?
Yes, but you won't have functional wipers, which is dangerous in rain or snow.
Will this code come back after being cleared?
If the issue isn't fixed, it will return after the next cycle.
Why does this code appear with other codes?
Wiper codes often show up with others related to the same system or control unit faults.
