2010 Subaru Forester Wiring Diagram 2010 radiator fans will not turn on? i am looking to diagnose why the radiator fans are not turning on when the engine is running at operating temp. i have tested the fans motors themselves and they turn on when powered. i have replaced the oil temp sensor, i have replaced the main fan relay, the sub fan relay and the third relay related to. Shield & sensor ground joint connector oxygen sensor at model : to f b fuse no. 11. mt model : to clutch switch (cruise control) to stop & brake switch. to cruise control switch. to cruise control warning light to cruise set indicator light to a c pressure switch to a c relay to a c switch to blower fan switch to main fan relay to sub fan relay. Nspectionoperating condition:radiator fan operates depending on the radiator fan speed related to engine coolant temperature or the ra diator fan speed related to a c compressor load, whichever. is higher as a load condition. radiator fan speed relate. kgf cm2, 725 psi)diagnosis:radiator main and sub fans do not rot. Here's what i have done: 1. checked relays f28 and f66 as well as both fuses in f27 in attached diagram. i used my multimeter and once i activated the relays resistance went down to zero. resistance of fuses was zero as well. 2. after relays were pulled, jumped with a wire and both fans kicked on immediately. 3.
