Restore smooth and reliable window operation with this OE Match Electric Window Motor with 8-Tooth Cog, manufactured as a direct replacement. Produced to OE-style specifications, this electric window motor provides the power required to raise and lower the door glass, ensuring consistent operation and correct engagement with the window regulator mechanism.

Fits:

• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L

Over time, electric window motors are subjected to continual use, vibration, moisture, and electrical wear. Internal motor components can weaken, while the drive gear and bearings may wear, resulting in slow, erratic, or complete loss of window movement. Replacing a faulty window motor restores dependable operation and helps prevent additional strain on the window regulator assembly. This OE Match component is ideal for routine maintenance, electrical repairs, and Porsche restoration projects.  

What This Product Does:

• Powers the raising and lowering of the door window.
• Drives the window regulator via the 8-tooth drive cog.
• Provides smooth and consistent window movement.
• Helps maintain reliable operation of the electric window system.
• Replaces worn, seized, or failed original window motors.
• Reduces strain on the window regulator mechanism.
• Provides an OE-style fit and dependable quality.

Symptoms Of Wear Or Failure:

• Electric window operates slowly.
• Window stops part way through its travel.
• Window fails to move despite switch operation.
• Grinding or clicking noises from inside the door.
• Intermittent window operation.
• Motor runs without moving the window.
• Excessive play or wear in the drive cog.
• Complete failure of the electric window motor.

Why Replacement Matters:

• The electric window motor is responsible for converting electrical power into the mechanical movement needed to raise and lower the door glass. A worn or failed motor can leave the window stuck open or closed, place unnecessary strain on the regulator mechanism, and reduce the convenience and security of the vehicle.
• Replacing the window motor restores smooth, reliable window operation and helps protect associated regulator components from premature wear. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match electric window motor with an 8-tooth cog provides the correct fit, dependable quality, and long-lasting durability, making it an excellent choice for Porsche maintenance, electrical repairs, and restoration projects.

Window lifter rail rubber seal fits into the window lift rail.
The window lift rail seal is an rubber strip designed to fit into the lower window lift rail, providing proper cushioning and grip for the door glass on Porsche 911, 964, and 993 Coupe models. It matches the original seal profile, hardness, and length to ensure smooth window operation and secure glass seating inside the lift channel.

Fits:
Porsche 911 1969 - 1989 ALL
Porsche 964 1989 - 1994 ALL
Porsche 993 1994 - 1998 Coupe

Diagram ref no 15.

The rubber sealing strip that sits inside the window lift rail (glass carrier channel). It grips the bottom edge of the door glass, ensuring the pane is securely held in place as the window regulator raises or lowers it.

This seal:
• Ensures the door glass is firmly clamped within the lift rail.
• Prevents rattling, vibration, or movement of the window during driving.
• Provides a cushioned interface between the metal rail and glass to prevent scratching or stress cracks.
• Helps maintain smooth and reliable window movement throughout the regulator’s travel.

Over time, the original window lift rail seal can harden, flatten, or crumble, causing the door glass to loosen inside the rail. This leads to rattling, uneven window movement, and even scratching or damage to the lower edge of the glass. Replacing the seal ensures the window is held firmly and quietly, restoring smooth operation and protecting both the regulator and the glass from premature wear.

Replace this seal if:
• The window moves inconsistently or tilts during operation.
• You hear rattling or vibration inside the door.
• The seal is visibly cracked, hardened, or missing sections.
• Glass shows scratches near the lower edge.
• You are replacing the regulator or restoring door internals.
