Switch a high-current circuit from a low-current trigger with the Standard Ignition HVAC Blower Motor Relay RY-233 (cataloged as a multi-function relay), a direct-fit FSR relay for the 1987-1995 Isuzu FSR and other listed Isuzu medium-duty trucks. This 12-volt relay uses an electromagnetic coil to open and close its contacts, letting a small control current switch a larger load.
If a failed relay is the cause of a circuit that won't power on or works intermittently, this replaces it. Listed as both an HVAC blower motor relay and a multi-function relay. Fits 1987-1995 Isuzu FSR, 1988-1995 Isuzu FTR, 1988-1990 Isuzu FVR, and 1995 Isuzu FRR. Country of origin: Japan.

This part cross-references / interchanges with the following part numbers:
What vehicles does the RY-233 relay fit?
It fits the 1987-1995 Isuzu FSR, 1988-1995 Isuzu FTR, 1988-1990 Isuzu FVR, and 1995 Isuzu FRR. Check the Buyer's Guide tab to confirm your vehicle.
Is this a Ftr relay?
Yes—the RY-233 is a direct-fit Ftr relay for 1988-1995 Isuzu FTR trucks, among the other listed Isuzu applications.
What does this relay do?
It uses an electromagnetic coil to switch a higher-current circuit on and off from a low-current control signal within the 12-volt system.
What are signs this relay may need replacing?
If the relay is the cause, the controlled circuit may fail to power on, operate intermittently, or the relay may click or buzz without switching cleanly.
Does it include a mounting bracket?
Yes, a mounting bracket is included. It has four male blade terminals across two rectangular female connectors and operates on 12 volts.
