What Does B1411 Mean?
This code indicates the Body Control Module (BCM) has detected an open circuit in the driver's side power window motor circuit. An open circuit means there is a break in the electrical path preventing current flow to the window motor. This prevents the BCM from operating the driver's power window, either in the up or down direction.
Common Causes
35%
Broken or corroded wiring between BCM and window motor, often at door hinge flex point
30%
Failed driver power window motor with internal open circuit or brush wear
20%
Corroded or loose connector terminals at window motor or door harness
10%
Failed master window switch with open contacts or internal failure
5%
Blown fuse or open circuit in BCM power distribution to window circuit
Diagnostic Steps
1
Step 1: Inspect window motor fuse in fuse panel and verify continuity. Check for battery voltage at fuse output with ignition on.
2
Step 2: Remove driver door panel and visually inspect window motor connector and wiring harness for corrosion, damage, or broken wires, especially at door hinge flex area.
3
Step 3: Disconnect window motor connector and use multimeter to test for voltage at connector (BCM side) when operating window switch. Should see 12V in one direction, reverse polarity in other direction.
4
Step 4: If voltage present at connector, test window motor by applying direct 12V power and ground to motor terminals. Motor should run in both directions when polarity is reversed.
5
Step 5: If no voltage at motor connector, backprobe master window switch connector with multimeter while operating switch to verify switch operation and continuity through switch contacts.
6
Step 6: If switch operates correctly but no voltage at motor, inspect and test wiring continuity between BCM, door harness, and motor connector for open circuits using ohmmeter.

The most common cause of B1411 (Driver Power Window Motor Circuit Open) is: Broken or corroded wiring between BCM and window motor, often at door hinge flex point
Typical repair costs for B1411 range from $150 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving as this only affects convenience features. However, lack of driver window operation may prevent communication with toll booths, parking gates, or emergency situations requiring window operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1411 to identify the root cause.
