What It Helps Resolve

• HVAC relay failure causing intermittent climate control operation
• Noisy or stuck relay switching in the control circuit
• Electrical interruption to temperature control functions
• Relay-related loss of power to the HVAC system
• Faulty 5-terminal relay replacement needs on select Toyota and Lexus models

Installation Notes

Verify the connector shape, terminal count, and relay position before installation. RY-475 uses a square connector with 5 male blade terminals and is not a continuous-duty relay. Confirm the vehicle’s relay location and application notes, especially on listings marked 5 Term ABS Relay or No. 2/No. 3, before swapping the part.

Quality Assurance

Standard Ignition supplies this relay as a direct replacement electrical component for the listed applications. The part number RY-475 is also referenced by OE-style interchange numbers for cross-checking during diagnosis and ordering.
