Diagram Ref No 1
The regulator sits inside the door and converts the rotational movement produced by the electric window motor into controlled vertical movement of the door glass.
Part number 99754207502 is for the left-hand side, while 99754207602 is for the right-hand side.
These regulators are supplied as the mechanical window-lifting assembly and do not include the electric window motor.
The Porsche 997 uses frameless door glass on applicable Coupe and Targa models, making accurate window positioning particularly important. The regulator must guide the glass smoothly through its full travel while maintaining the correct alignment against the door seals and roof aperture.
Over time, the regulator mechanism can wear through repeated operation. Cables can stretch or fray, pulleys can deteriorate, guides can wear and retaining components can loosen or break.
Typical symptoms include slow or uneven glass movement, clicking or grinding noises, the window dropping into the door, glass sitting crooked, or the motor operating without moving the glass.
Replacing a worn or failed regulator restores correct window support and movement while allowing the original electric motor to be reused if it remains serviceable.
What This Product Does:
The Window Regulator supports and moves the door glass when the electric window system is operated.
Its main functions are to:
- Raise the door glass.
- Lower the door glass.
- Keep the glass properly supported.
- Guide the glass through a controlled vertical path.
- Maintain correct glass alignment.
- Transfer movement from the electric motor to the window.
- Support the frameless-glass drop and raise function where applicable.
- Hold the glass securely in its selected position.
- Replace a worn, damaged or failed original regulator mechanism.
Symptoms Of Wear Or Failure:
Common symptoms include:
- Window moving slowly.
- Window moving unevenly.
- Glass tilting during operation.
- Grinding noise inside the door.
- Clicking noise.
- Scraping noise.
- Window dropping suddenly.
- Glass falling into the door.
- Motor running but glass not moving.
- Window becoming stuck.
- Window stopping halfway.
- Glass failing to close completely.
- Excessive glass movement.
- Window not sealing correctly.
- Increased wind noise.
- Water ingress around the door glass.
- Window drop function operating incorrectly.
Why Replacement Matters:
Replacing a worn or failed Window Regulator helps restore:
- Smooth window operation.
- Correct glass alignment.
- Reliable raising and lowering.
- Proper glass support.
- Correct sealing against weatherstrips.
- Reduced wind noise.
- Reliable frameless-window operation.
- Secure retention of the door glass.
