Windshield Wiper Control Relay Module

Keep your front glass clear in any weather ☔ with a reliable wiper relay module designed for Toyota systems. This small electrical unit controls the wiper motor speeds, intermittent wipe timing, and park position, so each sweep starts and ends cleanly. Built to OEM-grade standards, it restores factory wiping performance and protects the switch and wiring from overloads ⚡.

Why you need it

When rain hits, you need steady, predictable wipers. The relay handles low/high speeds, interval delay, and washer sync. It prevents current spikes, improves motor life, and ensures quiet, smooth operation. Ideal as a preventive replacement on aging vehicles .

How it works

Inside is a control circuit and electromechanical contacts. The coil energizes to feed power to the wiper motor; the timer pulses for intermittent mode; the logic reads the park switch so blades stop at the bottom. It sits in the fuse/relay box for quick access .

What happens if it’s broken

Common symptoms: no wiper operation, stuck on one speed, dead intermittent mode, random stops mid-sweep, blown fuse, hot relay, or clicking with no blade movement. In heavy rain, failure can be a safety risk—replace at the first sign of erratic behavior.
