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.

  • Composite housing: A high-quality composite housing is designed to protect against harsh temperatures and demanding under-hood conditions.
  • Certified manufacturing: Built in TS16949 and ISO9001 certified facilities.
  • OE ignition expertise: Standard Ignition is a global manufacturer of original equipment ignition products. It keeps full quality control over the process, from individual components to the finished product.

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.
