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?
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.
