- Stops and Starts: The window pauses mid-way, then resumes at a different speed.
- Jerky Movement: The window moves in a jerking or uneven manner instead of smoothly gliding.
- Changes in Speed: The window’s speed fluctuates randomly during operation, speeding up or slowing down unexpectedly.
- Requires Extra Button Pressure: The window only moves at a normal speed if you press the button harder or repeatedly.
Physical Inspection Tips
Physical Inspection Tips guide you through assessing your car window motor. A bad motor can be a nuisance. Spotting the signs early saves time and money.
Visible Damage Or Disconnection
Start with a visual check of the window motor. Look for any clear damage. Signs of wear or corrosion are red flags. Check wires leading to the motor. They should be secure and intact.
Look for these:
- Corrosion on Motor Housing: Rust or corrosion on the motor’s surface could mean moisture exposure, potentially damaging internal components.
- Frayed or Exposed Wires: Wires leading to the motor should be fully insulated; any fraying or exposure could cause electrical shorts or malfunction.
- Loose Connections: Wires or connectors should be firmly attached to the motor; loose connections may disrupt power and affect window function.
- Broken or Cracked Components: Any cracks or breakage on the motor housing or mounting points indicate physical damage, likely affecting motor performance.
- Burn Marks or Smell of Burning: Signs of scorching or a burning smell around the motor suggest electrical issues, potentially caused by overheating or short circuits.
Testing Window Motor Connectivity
Testing the motor’s connectivity is a must. Use a multimeter for this test. Set it to the ohms setting and check for continuity. A lack of continuity suggests a bad motor.
Follow these steps:
- Turn off the car’s power.
- Disconnect the motor’s wiring harness.
- Place multimeter probes on the motor terminals.
- Read the multimeter. No reading means a bad motor.
- Prepare the Multimeter: Set the multimeter to the ohms (Ω) setting to measure continuity.
- Disconnect the Window Motor: Ensure the car is off, then disconnect the wiring harness from the window motor to safely test it.
- Test Motor Terminals: Place the multimeter probes on the motor’s terminals. Ensure a solid connection with each terminal.
- Check for Continuity: Observe the multimeter reading. A reading close to zero indicates continuity, meaning the motor circuit is intact. If there’s no reading or it shows “OL” (open line), it indicates a break in the circuit, suggesting a faulty motor.
- Reconnect the Motor: Once testing is complete, reconnect the motor and wiring harness.
Electrical Troubleshooting
Car windows not moving can be frustrating. Electrical troubleshooting is a good start. This checks your car’s window motor’s health. Simple steps can reveal issues. Let’s dive into the process.
