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.

Set of 3 rollers

Fits:
Porsche 914
Porsche 924S
Porsche 944 (also S, S2 and turbo)

Old electric windows become sluggish and sometimes stutter. This is often due to the worn roles that are clipped on the ends of the cross arms. They are worn, partly stuck and then no longer roll off at the lower edge of the pane. Partly the roles are also completely broken off. They are not individually available at Porsche and so there was no alternative than to look for a slightly better, used and still expensive windows.

With this set of three rollers and a teflon-containing (= PTFE) lubricant can be a window lifter (left or right) renew. The rollers are made of a durable thermoplastic material.

The regulator rollers guide the window mechanism smoothly along its tracks every time the window is raised or lowered. Over years of use, the original plastic rollers can become brittle, crack or wear flat, causing the window to bind, move unevenly or stop operating altogether. Replacing the rollers restores smooth movement while extending the life of the complete regulator assembly and window motor.

Ideal for preventative maintenance, restoration projects or repairing faulty window mechanisms, this OE Match repair kit provides a cost-effective alternative to replacing the complete window regulator.

What Does the Window Regulator Roller Repair Kit Do?

The window regulator rollers are responsible for guiding the regulator mechanism as it raises and lowers the door glass.

Their primary functions include:

• Providing smooth movement of the window regulator.
• Guiding the window mechanism along its tracks.
• Reducing friction within the regulator assembly.
• Supporting accurate window alignment.
• Reducing load on the electric window motor.
• Helping prevent regulator wear.
• Maintaining smooth and quiet window operation.

Properly functioning rollers are essential for reliable electric window performance and help minimise unnecessary wear on surrounding components.

Why Replace the Window Regulator Rollers?

Window regulator rollers experience constant movement and loading throughout the life of the vehicle.

Common reasons for replacement include:

• Worn or flattened rollers.
• Cracked or broken plastic rollers.
• Excessive friction.
• Binding window mechanism.
• Noisy window operation.
• Regulator overhaul.
• Preventative maintenance.
• Window restoration projects.

Replacing the rollers restores smooth regulator movement and helps avoid premature failure of the window motor and regulator assembly.

Symptoms of Worn Window Regulator Rollers

Common warning signs include:

• Slow window movement.
• Window sticking during operation.
• Jerky or uneven window travel.
• Clicking or grinding noises inside the door.
• Window tilting as it moves.
• Electric motor straining.
• Window failing to fully open or close.
• Visible damage to the regulator rollers during inspection.

Addressing worn rollers early can help prevent more expensive repairs to the regulator and electric window motor.

Benefits

• Restores smooth electric window operation.

• Eliminates sticking and uneven movement.
• Helps prolong the life of the window regulator.

• Window guide rails.
• Door glass guides.
• Window channels.
• Door moisture barrier.
• Door clips and fasteners.
• Window switches and electrical connections.

Clean the regulator tracks thoroughly and apply a suitable window regulator lubricant before reassembly. After installation, check that the window travels smoothly throughout its full range and that the glass aligns correctly with the door seals.
