How To Check Radiator Relay At Fred Ryan Blog 2) if no e fan operation, turn engine off, and disconnect connector x1797 from the fan unit. 3) with ignition on (engine still off), using multimeter, measure voltage in reference to chassis ground at pin#2, red blue wire. 4) check for continuity to ground at pin #1, brown wire. 5) test for voltage at pin #4, black blue small wire, in reference. Check for continuity between the common terminal and normally open terminal, as well as between the common terminal and normally closed terminal. apply power to the relay coil to verify that the switch opens and closes properly. measure the resistance across the relay coil terminals to make sure it falls within the specified range. inspect the.

The cooling fan relay is an electromagnetic switch that controls the power supply to the engine’s cooling fans. without it, the cooling fan won’t work. without the radiator fan, your engine can run hot and be at risk of overheating. a faulty relay can be caused by a bad relay control module, ants in the relay, or an electrical short. I spent several hours researching online and there are not many postings for the 2012 jk fan relays so i thought that i would share my experience. in the 07 12 model, the high speed relay was behind the driver side headlight. in the 2012 the relay was relocated next to the master cylinder along the driver side of the engine bay.
