B2195: Driver Window Motor Short to Ground
Code B2195 indicates that the Body Control Module (BCM) or Driver Door Module (DDM) has detected a short to ground in the power supply circuit for the driver's window motor (both up and down circuits). This prevents the window from operating and typically causes the circuit protection device (fuse or circuit breaker) to open, preventing damage to the wiring harness or module.
1. Commonly Affected Makes
2. Most Common Causes
- Chafed or pinched wiring for the window motor, often where the harness passes through the rubber boot between the door and A-pillar
- Driver window motor with an internal short to the motor housing
- Faulty DDM or BCM with an internal shorted driver
- Moisture or corrosion in the motor or module connector, bridging power terminals to chassis ground
- Repeatedly blown window circuit fuse due to the short
3. Symptoms You Will Notice
- Driver window does not move up or down
- Window fuse blows repeatedly
4. Step-by-Step Diagnosis
Check for blown fuse in the window circuit; replace and test if it blows immediately
Inspect wiring harness in the door hinge area for chafing or pinching
Disconnect the window motor connector and measure resistance to ground on the motor power terminals; a low reading indicates internal motor short
If motor and wiring are good, test DDM/BCM output signals for short to ground; replace module if faulty
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is safe to drive, but the driver window will not operate. The short may blow a fuse, but it does not affect other critical systems.
How much does it cost to fix?▼
Repair costs range from $100 to $400, depending on whether the issue is a chafed wire (low cost) or a faulty motor or module (higher cost).
