Now, replacing a window motor typically runs between $140 and $950, but the exact price depends on your vehicle, the type of motor, labor rates, and other factors.

How Much Does a Window Motor Replacement Cost?
On average, you’d pay around $140 to $950 for a window motor replacement.
Here’s the breakdown:
- Parts: $40 to $500
- Labor: $100 to $450 (The replacement process can take around 2 hours.)
6 Factors Affecting the Window Motor Replacement Cost
Here are the key factors that determine how much you’ll pay to replace a window motor:
- Vehicle make and model: Common cars (like a Toyota Corolla) use standard motors that are widely available and affordable. In contrast, luxury cars, SUVs, or vehicles with more advanced power window systems need larger and specialized motors, which can increase the cost.
- Type of motor design: In some cars, you can replace just the window motor, which keeps the cost down. However, if the motor comes integrated with the window regulator, you’ll need to replace the entire assembly. This drives up parts and labor costs, raising the overall repair bill.
- Door position: Front door window motors are usually larger and more expensive since they lift heavier glass. Meanwhile, rear door motors are smaller and often slightly cheaper.
- OEM vs aftermarket parts: OEM (original equipment manufacturer) motors are often more expensive but ensure a precise fit. Aftermarket motors cost less but may not perform well or last long.
- Location: Dealerships and shops in metro areas often charge higher rates than smaller independent garages or rural repair shops.
- Additional repairs: Sometimes, the issue isn’t limited to the motor. For example, you may need to repair other damaged parts, like a window regulator. This can add another $250 to $900 to the final bill.
Is It Worth Replacing a Faulty Window Motor?
Yes, replacing a bad window motor is essential for both convenience and safety.
Without it, you may be unable to roll your windows up or down. This can leave your car vulnerable to theft and weather damage.
4 Common Signs You Need a Window Motor Replacement
If you notice any of the symptoms below, call a mechanic ASAP:
- If you press the power window switch and the window doesn’t move at all, you may have a failed motor.
- A failing motor may make the window work intermittently. For example, it may move partway and then stop.
- If the window takes much longer than usual to roll up or down, the motor may be losing strength and struggling to power the regulator.
- When a window motor begins to fail, its gears wear down or slip, creating clicking, grinding, or whirring noises. Added resistance from a worn regulator, misaligned tracks, or dirt buildup can also worsen these sounds.
How Long Do Window Motors Last?
Window motors typically last 8 to 10 years under normal use.
However, they can fail sooner due to:
- Frequent window operation
- Dirt or debris in the window tracks
- Electrical problems, such as faulty window switches or corroded wiring
Is It Better to Repair or Replace a Window Motor?
You should consider replacing a failing window motor rather than trying to repair it. That’s because the motor comes sealed and isn’t designed for long-term repairs.
Replacing it will ensure reliable performance and prevent repeated breakdowns.
Can You Replace a Window Motor By Yourself?
Swapping out the window motor involves removing the door panel, disconnecting wiring, and working around delicate components. So, it’s not an easy task you can handle yourself. If done incorrectly, it can damage the motor and regulator or even cause electrical issues.
For peace of mind, it’s usually best to leave this repair to professionals.
Here’s how a qualified mechanic would replace the window motor:
- Park the car safely, turn off the ignition, and disconnect the battery.
- Remove the interior door panel carefully, detaching the trim pieces and fasteners.
- Disconnect the window switch wiring and peel back the protective water shield.
- Unbolt the old motor from the car door frame or regulator, then disconnect its wiring.
- Install the new motor, secure it with bolts, and reconnect the electrical connector.
- Refit the water shield and reinstall the door panel securely.
- Reconnect the battery and test the window to ensure smooth operation.
