What Does B1419 Mean?
This code indicates the Body Control Module (BCM) has detected an open circuit in the passenger side power window motor circuit. An open circuit means there is a break in the electrical pathway preventing current flow to or from the window motor. This affects the passenger door power window operation, typically resulting in the window being completely inoperative.
Common Causes
40%
Broken or corroded wiring between BCM/door module and window motor, particularly in door hinge area where wires flex repeatedly
30%
Failed window motor with internal open circuit or burnt brushes
20%
Corroded or loose connector terminals at window motor or door control module
10%
Failed door control module or window switch with internal open circuit
Diagnostic Steps
1
Step 1: Perform visual inspection of passenger door wiring harness, focusing on the rubber boot area between door and body pillar where wires commonly break from flexing. Check for visible wire damage, chafing, or broken insulation.
2
Step 2: Disconnect the passenger window motor connector and inspect for corrosion, pushed-back pins, or water intrusion. Use a multimeter to test for continuity between the motor terminals and measure resistance (typical window motor resistance is 3-8 ohms). No continuity indicates open motor windings.
3
Step 3: With connector still disconnected, backprobe the harness connector from the BCM/door module side. Check for battery voltage on the power supply circuit and good ground on the ground circuit when operating the window switch. Absence of voltage or ground indicates wiring or module fault.
4
Step 4: If power and ground are present at connector but motor failed resistance test, replace the window motor. If no power/ground at connector, trace wiring back through door harness using continuity testing to locate the open circuit.

Step 5: After repairs, reconnect all components and operate the window using both master and passenger switches. Clear codes and verify no DTCs return. Perform window auto-up/auto-down relearn procedure if equipped.
Estimated Repair Cost

The most common cause of B1419 (Passenger Power Window Motor Circuit Open) is: Broken or corroded wiring between BCM/door module and window motor, particularly in door hinge area where wires flex repeatedly
Typical repair costs for B1419 range from $150 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving as this only affects passenger window convenience operation. No immediate safety risk, though lack of window operation may be inconvenient for ventilation and could be a security concern if window is stuck in the down position.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1419 to identify the root cause.
