- Reconnect Wiring: Attach the harness connectors, ensuring a snug and secure connection. Verify polarity if applicable.
- Test Operation: Reconnect the battery and activate the window switch. Observe smooth movement from fully closed to fully open positions without excessive noise or resistance.
Maintenance Tips
- Regular Inspection: Check for visible wear on gears, bearings, and mounting hardware every 10,000 km.
- Lubrication: Apply a light silicone-based lubricant to the gear teeth once a year to reduce friction and noise.
- Electrical Checks: Inspect wiring for corrosion or fraying. Replace any damaged cables promptly.
- Limit Switch Calibration: If the window stalls prematurely, adjust the limit switches following the manufacturer’s calibration procedure.
Common Troubleshooting Scenarios
