Standard Ignition WP636 Wiper Switch

Standard Ignition WP636 is a new windshield wiper switch for vehicles equipped with direct-mount control and 12-volt electrical systems. It provides windshield washer spray, wiper delay, and wiper speed control in a black plastic finish with an illuminated display and indicator markings.

Compatible With select Lexus GS F, GS450h, GS350, and IS350 applications, this WP636 switch is built for vehicles that do not use rain-sensitive wipers. It is a direct replacement for the original switch and uses a 3-connector, 22-terminal blade-style design.

Detailed Description

The Standard Ignition WP636 is a windshield wiper switch engineered for driver control of washer spray, intermittent delay, and wiper speed functions. It is a direct-fit replacement with a square and rectangle connector shape, male blade terminals, and a black plastic housing. The switch includes visible indicator markings and is intended for vehicles that use a conventional wiper control layout rather than rain-sensing operation. This part cross-references OE-style numbers such as 8465230650 and WS6891 for the same application.

Fits 2018 Lexus GS F, N/A. Fits 2014-2018 Lexus GS450h, N/A, not compatible with vehicles equipped with Rain Sensitive Wipers. Fits 2018 Lexus IS350, N/A. Fits 2014-2015 Lexus GS350, N/A, not compatible with vehicles equipped with Rain Sensitive Wipers. Standard Ignition WP636 is a practical replacement when the original Lexus GS F, GS450h, GS350, or IS350 wiper switch no longer responds correctly.

What It Helps Fix

  • Intermittent wiper operation that no longer changes delay settings
  • Loss of windshield washer spray control from the stalk switch
  • Wiper speed selection that does not respond properly
  • Broken, worn, or intermittent switch contacts
  • Cracked or faded original switch housing and markings

Installation Notes and Tips

Verify the vehicle is not equipped with Rain Sensitive Wipers before ordering. Match the connector style, terminal count, and control layout to the original switch before installation. Because this is a direct replacement, it should be compared against the factory unit for connector shape, display style, and included functions such as washer spray and delay control.

Quality Assurance

Standard Ignition supplies this WP636 as a new replacement switch built to match the listed OE-style application requirements for Lexus GS F, GS450h, GS350, and IS350 models.
