Common Problems This Relay Can Address

• Starter relay failure that prevents proper circuit operation
• Intermittent HVAC temperature delay relay performance
• Electrical contact wear in aging relay assemblies
• Relay replacement needs on Toyota and Lexus HVAC-related circuits
• Fitment-specific service on vehicles using OE-style 4-terminal relay layouts

Installation Notes and Tips

Verify the connector shape, terminal count, and OE reference before installation. RY-290 uses a push-on mounting style and a 4-terminal blade layout, so the replacement relay must match the original socket configuration. Confirm the vehicle’s relay stamping or OE number when servicing applications such as Toyota Celica, Lexus RX330, or Toyota Tacoma, especially on models with fitment notes like heated mirror or specific relay positions.

Quality Assurance

Standard Ignition supplies this relay as an OE-style replacement component for listed applications. Confirm fitment against the vehicle year, make, model, and relay notes before ordering to ensure correct service on the intended Toyota, Lexus, Scion, Pontiac, Chevrolet, or Dodge application.
