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.

  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.
