Diagram ref no 17

Fitted inside the door, the electric motor drives the window regulator mechanism, allowing the glass to raise and lower smoothly when the window switch is operated.

Available in separate left and right-hand versions, this aftermarket replacement is ideal for repairing slow, intermittent or completely inoperative electric windows.

What Does It Do?

The electric window motor converts electrical energy into mechanical movement to operate the door window regulator.

When the driver presses the window switch, electrical power activates the motor, which turns the regulator mechanism to raise or lower the glass.

The motor works alongside the window regulator, guide channels and electrical switches to provide controlled window movement.

Why Is It Important?

A functioning electric window motor ensures the side window can be opened and closed reliably.

A worn or faulty motor may cause:

• Windows moving slowly or unevenly
• Intermittent operation when pressing the switch
• Clicking or humming without window movement
• Windows stopping partway through travel
• Complete failure to raise or lower the glass
• Difficulty closing the window securely

These symptoms may also be caused by worn regulators, faulty switches, damaged wiring or stiff window guides.

Why Do Electric Window Motors Fail?

After years of operation, the motor's internal electrical and mechanical components can deteriorate.

Common causes include:

• Worn internal motor brushes
• Corrosion from moisture entering the door
• Damage to internal gears or drive components
• Electrical contact deterioration
• Excessive resistance from a stiff window regulator
• Age-related wear from repeated operation

A binding regulator can place additional strain on the motor and shorten its service life.

When Should It Be Replaced?

Replace the window motor when testing confirms that it no longer operates correctly or cannot reliably drive the window regulator.

Before replacing the motor, inspect the window switch, wiring connections, fuses and regulator mechanism to rule out other faults.

A replacement motor is particularly useful during classic Porsche door restoration or when repairing an electric window that has stopped functioning.

Installation Notes

Remove the door trim carefully to access the window motor and regulator assembly.

Support the window glass before disconnecting the motor and inspect the regulator mechanism for wear, damage or excessive resistance.

Fit the replacement motor securely and reconnect the electrical wiring.

Check that the window travels smoothly through its full range without binding or unusual noises before refitting the door trim.
