Radiator Fan Control Module

Located next to ECM (Prelude) or in left side kick panel (Accord), radiator fan control module works with ECM to determine when to activate the cooling fans. On Accord, module applies voltage through fuse No. 21 (A/C) and fuse No. 34 (radiator) to fan relays when ECM indicates A/C switch is in ON position. On Prelude, module applies voltage through fuse No. 45 (A/C) and fuse No. 47 (radiator) to fan relays when ECM indicates A/C switch is in ON position.
