Driver Window Motor Short to Ground
The B1413 code indicates that the driver door control module has detected a short to ground in the driver side power window motor circuit. This code is specific to Korean manufacturers, particularly Hyundai and Kia, which use this numbering in their body and comfort systems (B-codes). The short to ground prevents the window motor from operating correctly, as current is diverted directly to ground before reaching the motor, or the motor itself has an internal insulation failure.
1. Commonly Affected Makes
2. Most Common Causes
- Driver window motor with internal coil shorted to ground
- Wiring in the motor circuit (terminals 1 and 2 of the motor connector) with damaged insulation contacting chassis ground
- Window motor connector with corroded or moisture-contaminated pins causing a ground leak
- Driver door control module (DM) with a burned or internally damaged output transistor
- Door harness with a wire section worn through by friction at the door hinge area
3. Symptoms You Will Notice
- Driver side window does not move or operates intermittently
- Window may move slowly or stop working after a few cycles
4. Step-by-Step Diagnosis
Check for technical service bulletins (TSBs) related to window motor or door module issues
Visually inspect the door harness and motor connector for damage, corrosion, or chafing
Test the window motor by applying direct battery power and ground to its terminals; if it does not run, replace the motor
Measure resistance between each motor terminal and chassis ground; a reading below 10k ohms indicates a short to ground
If motor tests good, check for short to ground in the wiring between the door module and motor connector
If wiring is intact, suspect a faulty driver door control module
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is safe to drive, but the driver window will not operate properly. The issue does not affect vehicle safety systems.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, depending on whether the motor, wiring, or control module needs replacement.
