Common Window Motor Issues & Maintenance Guide

Signs of Power Window Motor Failure

Slow or Irregular Movement:
If your window moves slower than usual or operates at inconsistent speeds, this is often one of the first signs of a failing window motor.

Unusual Sounds:
Grinding, clicking, or whirring noises during operation typically indicate worn motor gears or debris in the mechanism.

Window Only Works Sometimes:
Intermittent operation is a common symptom of a failing motor or faulty switch. The window may work perfectly one moment and not respond the next.

Motor Works But Window Doesn't Move:
If you hear the motor running but the window doesn't move, this could indicate stripped gears within the motor assembly.

Requires Multiple Attempts:
When you need to press the window switch several times to get a response, this often indicates a failing motor or electrical connection.

Maintenance Schedule

Regular Inspection (Every 6 months):

• Listen for unusual noises during operation
• Check for smooth movement
• Clean window tracks and channels

Preventive Maintenance (Annually):

• Lubricate window tracks and regulators
• Check and clean electrical connections
• Test all window positions and speeds

Long-term Care:
While window motors don't have a specific replacement schedule, they typically last 8-12 years under normal use. Regular maintenance can extend their lifespan significantly.

Professional Inspection Recommended When:

• Vehicle reaches 100,000 miles
• Windows show any signs of irregular operation
• After any collision repair
• If vehicle has been exposed to flooding

Note: Maintenance schedules may vary based on vehicle make, model, and operating conditions. Consult your vehicle's manual for specific recommendations.
