Check fitment for your specific vehicle (model, year, engine) before ordering. Match part number 9J0845019BY or 9J0845020BY to the vehicle identification number, required door position and original glazing specification.

What Is This Part?
This is the glass pane that forms the opening side window in a front door. It works with the window regulator, runners and surrounding seals, which support its movement and seating. During replacement, these supporting components should also be inspected, particularly if the old glass is scratched or loose. Glazing specifications can differ between vehicle configurations, so the correct pane must be identified by more than model name alone.

What Does This Part Do?

• Provides an outward view: Forms the transparent section of the front door window opening.
• Closes the opening: Works with the surrounding seals when the window is raised.
• Forms the moving window pane: Works with the regulator and runners as the window opens and closes.

Why Replace This Part?
Replacement may be needed when the existing pane is cracked, chipped or heavily scratched. Assess the extent and position of any damage before deciding on the repair, including whether surface marks interfere with the view through the window.

If the glass is scored, sits loosely or does not seat correctly, inspect the regulator, runners, fixings and seals before fitting a replacement. Renewing the pane alone may not address the underlying cause, and poor alignment or damaged supporting components need attention as part of the repair.

When to Replace This Part?

• Cracked or broken glass: Inspect visible fractures and damage to the pane or its edges.
• Chips: Have chipped areas assessed to establish whether replacement is required.
• Heavy scratching: Consider replacement where scoring significantly affects the view through the glass.
• Loose seating: Check the runners, mountings and regulator; replace the pane only if its condition warrants it.
• Repeated scoring: Identify and correct the source of contact before installing new glass.

Where Is This Part Fitted?
Location: In the front door window opening, supported by the door's window lifting and guiding components. Confirm the required door side against the part number before ordering.

FAQs

• How do I confirm the correct window?
  Match part numbers   9J0845019BY & 9J0845020BY against your vehicle identification number, required door position and original glass specification.
• Is the tint or glass specification confirmed?
  Confirm the tint, glass construction and any coating against the vehicle specification before ordering.
• Are channels, seals or fittings included?
  Confirm the contents before planning the repair, and check whether existing supporting components can be reused.
• Will new glass resolve a loose window?
  Not necessarily. Inspect the regulator, runners, fixings and seals to establish why the window is loose before replacing the pane.
