Standard Ignition A/C Compressor Control Relay,HVAC Blower Motor Relay,HVAC Relay,Ignition Relay P/N:RY-146
Handle the A/C compressor's switching duty with the Standard Ignition RY-174 A/C Control Relay, a direct-fit replacement for the 1982-1985 Honda Accord, 1982-1985 Honda Civic and 1982-1985 Honda Prelude. A relay is an electrically operated switch. A small control current energizes it so it can close the higher-current circuit for the A/C compressor. Standard Ignition catalogs this unit as an A/C compressor control relay, HVAC relay, main relay and power window relay.
This relay may need replacing if the A/C compressor won't engage, the air conditioning works only some of the time, or the relay no longer clicks when the A/C is switched on. Fuses, switches and wiring can cause the same symptoms, so diagnose the circuit before replacing parts. Engine details for each application are in the Buyer's Guide tab.
