Take back control of your wipers with the Standard Ignition Windshield Wiper Switch WP591 — the driver-operated switch that signals the wiper system and lets you select your wiper settings. It installs as a direct-fit replacement for the 2013-2020 Ford Fusion, 2015-2023 Ford Mustang, 2019-2020 Ford Police Responder Hybrid, 2019-2020 Ford SSV Plug-In Hybrid, and 2013-2020 Lincoln MKZ (see the Buyer's Guide tab for the full list).

  • Built to OE spec: produced under complete quality control and manufactured to OE specifications for proper fit, form, and function.
  • Copper alloy conductors: deliver superior electrical conductivity with low resistive losses.
  • Direct-fit OE-replacement: if a failed wiper switch is the cause of your lost wiper control, this switch replaces it and helps restore wiper operation.
  • Robust design: high-grade materials engineered to meet the demands of today's service professional.

If your wipers won't turn on, get stuck on one speed, or the intermittent/wash settings no longer respond, a worn wiper switch may be the cause — diagnose the circuit before replacing.
