What Is This Part?

This is a combined electrical switch assembly for the driver's door, bringing together window, door-mirror and luggage compartment controls. Operating its buttons provides commands to the associated vehicle electrical systems. The switch assembly works with the wiring, connectors and control equipment serving those functions. When investigating a fault, the condition of the controls should therefore be assessed alongside the connected system rather than assuming that an unresponsive window or mirror proves the switch has failed.

What Does This Part Do?

• Window control: Provides the driver's inputs for raising and lowering the electric windows.
• Mirror control: Provides inputs for adjusting the door mirrors.
• Luggage compartment control: Provides the driver's switch input for the luggage compartment function.
• Combined operation: Groups these controls together within the driver's door switch assembly.
  
  Why Replace This Part?

Replacement may be appropriate when testing traces intermittent or failed operation to the switch assembly. Repeated use, contamination, moisture exposure or physical damage can affect electrical contacts, buttons or their supporting mechanism. A button that sticks, has excessive play or only responds when pressed at a particular angle warrants inspection.

Check the connector, door wiring, electrical supply and affected mechanism before replacing the assembly. A damaged loom, poor connection or fault elsewhere in the system can produce similar symptoms. Replacing the switch will not correct a separate window regulator, motor or wiring fault.

When to Replace This Part?

• Intermittent response: A control requires repeated presses or works only at certain pressures.
• Lost window command: A window responds in only one direction, or operates from another control but not this assembly.
• Damaged buttons: A switch is cracked, loose, sticking or no longer returns normally.
• Mirror or luggage compartment faults: The relevant control fails to respond and diagnosis identifies the assembly as the cause.
• Moisture or connector damage: Inspection reveals contamination, corrosion or damaged terminals requiring attention.
  
  Where Is This Part Fitted?

Location: Within the driver's door interior switch panel. The stated application covers the driver's side on either left-hand-drive or right-hand-drive cars; check the existing assembly and connector before fitting.

Technical Details

• Installation position: Driver's side, LHD or RHD.
• Equipment restriction: For cars without alternative drive system (I0K0).
• Production cut-offs: Panamera up to 25/05/2018; Cayenne up to 27/05/2018.
  
  FAQs

• Could an unresponsive window be caused by the regulator?
  Yes. Inspect the window mechanism and motor as well as the switch, particularly if there is grinding, abnormal glass movement or mechanical noise.
• What should be checked before replacing the switches?
  Check the electrical supply, connector condition and door wiring, then test whether the affected function responds correctly to its control input.
• Is the model name alone enough to confirm fitment?
  No. Match the existing switch reference, connector, driver's-side arrangement, production date and equipment specification. Resolve any conflict with the I0K0 restriction before ordering.

  What Is This Part?

This is the passenger-operated electrical switch for the electric window regulator. The switch provides the opening and closing command, while the motor and regulator carry out the movement of the glass. Its button and internal switching mechanism form the user-operated part of that system. Replacing it is appropriate when testing identifies a fault in the switch rather than in the wiring, motor or lifting mechanism.

What Does This Part Do?

• Commands window opening: Allows the passenger to request downward movement of the glass.
• Commands window closing: Provides the corresponding control for raising the glass.
• Provides local control: Gives the passenger access to the window function from their own switch.
  
  Why Replace This Part?

Repeated use, dirt or moisture can affect the switch mechanism and its electrical contacts. A sticking button, broken actuator or unreliable contact may prevent the window from responding consistently, even when the motor and regulator remain serviceable.

Confirm the cause before replacing the switch. Loose connectors, damaged door wiring and faults elsewhere in the window system can produce similar symptoms. OE Match supplies Porsche-focused replacement parts; selecting the correct reference and switch version remains important.

When to Replace This Part?

• Intermittent response: The window responds only after repeated presses or when the button is held at a particular angle.
• One-direction operation: The window opens but will not close, or closes but will not open, and testing identifies the switch as the cause.
• Mechanical damage: The button is cracked, loose, sticking or no longer returns normally.
• Different response between controls: The window works from another control but not from the passenger switch; inspect the switch and its connections.
• Visible deterioration: Moisture damage, corrosion or damaged terminals are found during inspection.
  
  Where Is This Part Fitted?

Location: At the passenger-side electric window control position in the door trim, connected to the window-control wiring. Check the existing mounting and connector before fitting.

Technical Details

• Position: Passenger side.
• Finish: High-Gloss Black/Black.
• Supply: Supplied individually.
  
  FAQs

• Could the fault be the regulator instead? Yes. Grinding, uneven glass movement or glass that drops warrants inspection of the regulator and motor rather than assuming the switch has failed.
• What should be checked first? Check the relevant fuse, connector condition and door wiring, then test the switch using the appropriate vehicle-specific procedure.
• Does operation from another switch prove this one is faulty? No. It helps narrow the investigation, but the passenger switch connections and wiring still need checking.
