Send power to your A/C compressor clutch whenever the climate system calls for cooling with the Standard Ignition A/C Compressor Clutch Relay, part number RY-1620. It fits many vehicles, among them the 2011-2012 Ram 1500, 2007-2017 Jeep Wrangler and 2009-2020 Dodge Grand Caravan. It is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full vehicle list and engine details.
This relay works as an electrically controlled switch. A low-current signal energizes it, and its contacts close to supply power to the compressor clutch circuit. The catalog also lists it as an A/C compressor control relay and an HVAC blower motor relay.
Signs this relay may need replacing include a compressor clutch that won't engage, air from the vents that stays warm, or cooling that cuts in and out. Other faults can cause the same symptoms, so diagnose the system first. If a failed relay is the cause, RY-1620 replaces it.
