Buying advice

When choosing a door relay, consider the current draw of your door actuator, the operating temperature range, and whether the relay’s mounting style matches your vehicle’s panel. Higher current ratings (30A and above) are ideal for heavy-duty or aftermarket doors, while 10-12A relays suit standard OEM setups. Always verify the relay’s polarity and connector compatibility to avoid wiring issues.
