What Does B1467 Mean?
This code indicates the Body Control Module (BCM) has detected an abnormal short-to-battery voltage condition in the windshield wiper motor's high/low speed control circuit. The control module identified that battery voltage is present on the wiper motor speed control circuit when it should not be, suggesting current is flowing directly from the battery through a damaged wire, failed relay, or faulty motor. This prevents proper speed control and can cause wipers to operate erratically or continuously.
Common Causes
40%
Damaged or chafed wiring harness between BCM and wiper motor causing direct battery voltage exposure
30%
Failed wiper motor with internal short circuit to power supply
20%
Stuck or shorted wiper relay providing constant battery voltage to motor circuit
10%
Corroded or damaged wiper switch assembly causing internal short to battery voltage
Diagnostic Steps
1
Step 1: Perform visual inspection of wiper motor wiring harness from BCM to motor, checking for chafed insulation, melted wires, damaged connectors, or signs of wire contact with metal body panels or hot engine components
2
Step 2: Disconnect wiper motor connector and use a digital multimeter to measure voltage on the hi/low speed control wire at the harness side with ignition on and wiper switch off - should read 0V; if battery voltage present, fault is in wiring or control module
3
Step 3: With motor disconnected, check resistance between the suspected short circuit wire and battery positive terminal - should read open circuit (OL); low resistance indicates short in harness; inspect relay operation by listening for clicking and measuring relay output terminals
4
Step 4: If wiring tests normal, measure resistance across wiper motor terminals at motor connector - compare to manufacturer specifications (typically 2-6 ohms per speed); extremely low resistance or continuity to motor housing indicates internal motor short
5
Step 5: Clear codes, reconnect all components, and operate wiper system through all speeds while monitoring live data for abnormal voltage or current draw; verify proper operation and confirm no code returns

The most common cause of B1467 (Wiper Hi/Low Speed Circuit Motor Short To Battery) is: Damaged or chafed wiring harness between BCM and wiper motor causing direct battery voltage exposure
Typical repair costs for B1467 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is generally safe to drive, but windshield wiper functionality may be compromised or inoperative, which creates a significant safety hazard in rain, snow, or reduced visibility conditions. Repair should be completed before driving in inclement weather.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1467 to identify the root cause.
