Application Details
This Standard Ignition RY-55 relay is used across a wide range of Isuzu, Acura, Geo, Chevrolet, and Nissan applications, including HVAC automatic temperature control relay service and select fuel pump relay circuits. It fits 1984-2002 Isuzu Trooper, 1996-1999 Acura SLX, 1981-1995 Isuzu Pickup, 1991-1995 Isuzu Rodeo, and 1989-1994 Isuzu Amigo.

Common Uses
- Restoring HVAC relay operation in vehicles with automatic temperature control
- Replacing a failed fuel pump relay circuit component
- Addressing intermittent electrical switching in 12-volt systems
- Correcting blower, control, or relay-trigger issues tied to the circuit
- Replacing worn 5-blade relay hardware in older import applications
Installation Notes
Verify connector shape, terminal count, and amperage rating before installation. The RY-55 uses a male rectangular connector with 5 blade terminals, so the vehicle harness must match that layout. Confirm the exact application notes for your vehicle, including special cases such as Park/Neutral Position, heater, ABS relay, or automatic transmission spark control relay references. Fits 1984-2002 Isuzu Trooper, 1996-1999 Acura SLX, and other listed applications by year and model.
Quality Assurance
Standard Ignition supplies this relay as a replacement electrical component for listed import and domestic applications. The RY-55 part number is used for catalog matching and service identification, and it is supported by the interchange references shown for application verification.
This part fits 207 vehicles
Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
