Wired up electric fan to pin #29 as per instructions. Fan will not turn on when temp of 172 is reached. Tablet indicates the fan comes on with the green light, however no fan start up. When ground out that terminal #85 on relay (E-street main harness pin #29) the fan turns on. So to my understanding, the relay is wired correctly. Changed the ecu to pin #30 and still same result. Verified continuity in all wiring to relay. Any help?
