Standard Ignition RY-233 blower motor relay for the 1995 Isuzu FRR and other vehicles switches power to the cabin blower motor. Also called an HVAC blower motor relay, it controls the power feed to the heater and A/C fan.
A blower that stays silent on some or all speeds, or cuts in and out, can point to the relay. A blown fuse, a worn blower motor or a damaged connector can be behind the same symptoms, so find the cause before buying. If a failed relay is the cause, this one replaces it.
The 1995 Isuzu FRR, the 1987-1995 Isuzu FSR and the 1988-1995 Isuzu FTR take this relay, one each, and it fits more vehicles besides. This listing is one relay. If your truck is not named here, look it up in the "Vehicles it fits" section.
