What This Product Does

This assembly groups the applicable console switches into one control interface. Supplied identification associates it with the sliding-roof arrangement for PR code 653, rather than a steering-column indicator or wiper stalk. The adjacent climate-control panel is a different component.

Functions

  • Accepts button inputs for the connected console functions.
  • Provides switching for the specified sliding-roof arrangement.
  • Replaces the corresponding original multiple-switch unit.

Technical Details

  • Brand: Genuine Porsche; part number: 99161395707DML.
  • Diagram identification: combined switch; multiple switch; centre console repair set.
  • Finish specified: Matt Black/hi-gloss chrome.
  • Application marking: COUPE PR:653; diagram quantity: 1.
  • Turbo / GT2 RS diagram row includes the model-year notation D - MJ 2014>> - MJ 2016.
  • Supplied supersession references: 99161395700DML, 99161395701DML, 99161395703DML and 99161395705DML.

Symptoms of Fault

Possible signs include inconsistent button response, repeated presses being needed, sticking controls, failed illumination or damaged trim. Moisture and poor terminal connections can produce similar behaviour, so these symptoms alone do not confirm a defective switch.

Why Replacement Matters

Renewal is appropriate when testing establishes that the switch itself causes unreliable operation. Retaining the correct assembly preserves the specified console layout and finish. Before replacement, assess the relevant fuse, supply voltage, wiring, connections and diagnostic information.

FAQs

Does this include the climate-control panel?
No; that panel and the neighbouring switches are separately identified components.

Can an intact-looking switch have an electrical defect?
Yes. Internal wear need not leave visible damage on the exterior.

What determines compatibility?
Verify 99161395707DML against the VIN, model year, body style and PR codes, including the supplied COUPE PR:653 requirement.

About Indicator / Wiper Stalk Switch

Indicator / Wiper Stalk Switches – Precision Control for Porsche Vehicles

Indicator and wiper stalk switches are key components of your Porsche’s steering column controls, managing essential driving functions such as turn signals, wipers, headlight flash, and sometimes cruise control. These multifunction switches provide seamless control at your fingertips, ensuring safe and convenient operation in all driving conditions.

At Design911, we offer a complete range of genuine and quality indicator and wiper stalk switches for Porsche models - including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each switch assembly is manufactured to exact specifications for perfect fitment, durability, and reliable performance.

What Do Indicator / Wiper Stalk Switches Do?
Mounted on the steering column, these stalk switches allow drivers to activate multiple functions without removing their hands from the wheel. Depending on the vehicle model, a stalk may control:

  • Turn signals and hazard lights for safe lane changes and signalling.
  • Windscreen wipers and washers for clear visibility.
  • Headlight beam and flash functions.
  • Cruise control or trip computer functions (on certain models).

These controls are ergonomically designed for intuitive use and play a critical role in driver safety and convenience.

Why Do Indicator / Wiper Stalk Switches Fail?

Over time, these frequently used switches can wear out mechanically or electrically due to:

  • Repeated use and mechanical fatigue causing broken contacts or worn pivots.
  • Moisture or dust ingress leading to corrosion and poor electrical contact.
  • Internal short circuits or cracked solder joints.
  • Loose or worn detents causing the stalk to feel sloppy or fail to engage.
  • Age-related material degradation in plastic components.

Common symptoms of failure include non-functioning indicators or wipers, intermittent operation, headlight flash issues, or the stalk feeling loose or unresponsive.

Why Replace Faulty Indicator / Wiper Stalk Switches?

A worn or malfunctioning stalk switch not only affects convenience but can also compromise safety by disabling critical systems such as indicators or wipers. Replacing the faulty component ensures reliable operation and proper communication with your vehicle’s electronic control systems.

Benefits of replacing include:

  • Restored operation of indicators, wipers, and lighting controls.
  • Improved driving safety and comfort.
  • Smooth, responsive stalk movement.
  • OEM-quality reliability and longevity.

Each replacement switch is designed to fit and function exactly like the original, maintaining your Porsche’s precision feel and ensuring dependable performance in all conditions.
