Testing fan system because it seems like it should have been on but wasn't. Ecu saw 203.
So I grounded out the blue wire by thermostat and both fans turned on.
I jumped out the sensor wires for the lower rad temp sensor and the relay clicks but no fan.
Resistor wires at fan harness connection was 7.5 ohm.
All testing was with engine not running with ignition in the on position.
What do I check next?
