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.

What Is This Part?

This is the combined control switch fitted in the driver's door panel for operating the electric windows and exterior mirrors. It provides the driver's inputs to the window and mirror systems, while the motors and window lifting mechanisms carry out the movement. This version is specified for vehicles with electrically retractable mirrors, including the listed memory and auto-dimming equipment combinations. Those equipment descriptions identify compatible vehicle configurations; replacing the switch does not add those features to a car without them.

What Does This Part Do?

Controls window movement: Provides the controls used to request electric window opening and closing.
Controls mirror adjustment: Allows the driver to select and adjust the exterior mirrors electrically.
Supports electrically retractable mirror operation: Provides the appropriate control arrangement for the listed folding-mirror equipment.
Combines everyday door controls: Brings the window and mirror functions together in one driver's-side switch assembly.

Why Replace This Part?

Repeated use, worn contacts, dirt or moisture can leave a window or mirror switch intermittent or unresponsive. Physical damage may also leave a button loose, sticking or unable to return properly. Replacement is appropriate when inspection and electrical testing identify the switch as the cause of the fault.

Check the connector, door wiring and affected motor or mechanism before replacing the assembly. A window that sticks or a mirror that will not move can have a fault elsewhere, so changing the switch without diagnosis may leave the original problem unresolved.

When to Replace This Part?

Repeated presses are needed: Window or mirror controls respond inconsistently or only under unusual pressure.
One direction does not respond: A window or mirror moves in one direction but not another, and testing identifies a switch fault.
Controls are damaged: Buttons are broken, loose, sticking or no longer operate normally.
Mirror selection is unreliable: The selector does not consistently engage the intended mirror.
Moisture or corrosion is present: Inspect the switch and connector, and address the source of any water ingress.
The housing will not seat securely: Check the switch housing and surrounding door-panel mounting points for damage.

Where Is This Part Fitted?

Location: In the driver's-side interior door panel, at the combined electric window and exterior mirror control position. It connects to the door's electrical wiring.

Technical Details

Position: Driver's side.
Finish: Matt Black/hi-gloss chrome.
Control functions: Electric window regulator and exterior mirror.
Mirror equipment: Electrically retractable mirrors, with the specified memory and auto-dimming combinations.

FAQs

Does an unresponsive window prove the switch is faulty?
No. Wiring, connectors, the window motor and the regulator can cause similar symptoms. Test the affected circuit before choosing replacement parts.
Why might a mirror move in only one direction?
A switch contact fault is one possibility, but wiring or a mirror motor fault can also prevent movement. Check the selected mirror and test the control output.
What should I compare before ordering?
Compare reference 99161315502DML, the connector, body style and mirror option codes with the existing installation.

What Is This Part?

This is a combined electrical switch assembly fitted into the driver's door panel. Its window buttons provide the operating inputs for the electric window system, while the mirror controls allow the driver to select and adjust the exterior mirrors. The assembly works with the vehicle's wiring, control electronics and the relevant motors and mechanisms. Matching the original control layout and mirror equipment is important because similar-looking switches can serve different vehicle specifications.

What Does This Part Do?

Operates the electric windows: Provides the driver's controls for requesting window opening and closing.
Selects the exterior mirror: Allows the driver to choose which mirror to adjust.
Controls mirror adjustment: Provides directional inputs to position the selected mirror glass.
Combines door-mounted controls: Brings the window and mirror operating switches together in one assembly.

Why Replace This Part?

Replacement may be appropriate when testing identifies worn contacts, internal switch damage or broken operating buttons. Repeated use, dirt and moisture can affect switch movement or electrical connections, potentially causing intermittent response or loss of an individual function. Physical damage can also leave a button loose or unable to return correctly.

A window or mirror that does not respond is not proof that this switch has failed. Inspect the connector, door wiring and relevant power supply, and check the motor or mechanism where necessary. OE Match provides a Porsche-focused replacement option once the switch has been identified as the cause and the correct version has been confirmed.

When to Replace This Part?

Intermittent response: A window or mirror control works only after repeated presses or when held at a particular angle.
Missing directional control: A window operates in only one direction, or a mirror responds on only one axis, and testing traces the fault to the switch.
Damaged buttons: A rocker, selector or operating surface is cracked, loose, sticking or broken.
Poor mirror selection: The selector cannot reliably choose the intended mirror.
Visible electrical deterioration: Moisture damage or corroded terminals warrant inspection of both the switch and its connector.
Poor mounting: Damaged retaining features prevent the assembly seating securely in the door panel.

Where Is This Part Fitted?

Location: In the driver's interior door panel, at the combined electric window and exterior mirror controls. It connects to the door wiring and is retained within the door trim assembly.

Technical Details

Control type: Combined electric window and exterior mirror switch assembly.
Position: Driver's side.
Finish: Matt Black / Hi-gloss chrome.
Equipment matching: Confirm mirror specification, control layout and electrical connection against the original assembly.

FAQs
Could an unresponsive window be caused by the regulator or motor?
Yes. Grinding noises, abnormal glass movement or a motor that runs without moving the glass require investigation of the window mechanism rather than assuming a switch fault.
What should be checked before replacing the switch?
Check the relevant power supply, connector condition and door wiring, including the section that flexes as the door opens. Electrical testing should follow the vehicle-specific repair procedure.
Does a mirror that moves in only one direction confirm switch failure?
No. The switch, wiring and mirror adjustment mechanism can produce similar symptoms. Test the affected circuit before choosing a replacement.
Can I choose this switch by appearance alone?
No. Compare the original reference, body style, mirror equipment and control layout as well as the vehicle model and year.
