Windshield Wiper Switch

The Painless Wiring Windshield Wiper Switch (Model 80173) is the intelligent electrical control center every custom automotive build and restoration needs when upgrading to a modern wiring harness. Whether you're installing a complete Painless Wiring system in a classic muscle car, hot rod, or modern vehicle undergoing extensive electrical modification, this switch replaces worn factory units or integrates seamlessly into aftermarket harnesses. Mechanics and fabricators rely on this component to restore clean, reliable windshield wiper control without the voltage drop and corrosion issues plaguing original equipment.

Built with Painless Wiring's precision-engineered construction, the 80173 switch handles the electrical demands of modern wiper motor circuits while maintaining consistent contact resistance that stock switches lose over time. The compact design measures 2.75 x 1.4 x 3.6 inches and weighs just 0.16 lbs, allowing it to fit into tight steering column housings or dashboard mounting points without requiring extensive modification. Heavy-duty internal contacts and reliable switching logic ensure that wipers respond instantly to operator input, eliminating the intermittent functionality and hesitation that plagues corroded factory switches in restorations.

Professional installers and DIY fabricators choose the Painless Wiring 80173 for resto-mod projects, full harness conversions, and electrical system upgrades where original wiper control architecture no longer meets modern reliability standards. The switch integrates directly with Painless Wiring complete harness systems, eliminating compatibility headaches and reducing diagnostic time on the bench. Installation requires basic electrical knowledge and standard hand tools—simply route the appropriate harness connectors to the wiper motor circuit and secure the switch body to your mounting location for years of dependable wiper operation.
