Front aux fans not coming on.
Wanted to get some feedback in here about this.
Replaced the two sensors (top for low speed bottom for high speed). Jump the leads at the sensor and the relays work and the fans come on. Turn on AC and the low speed fan comes on.
I originally though my thermostat was opening all the way and limiting the flow of coolant through the rad but just did a thermostat no change. New waterpump and hoses.
I let the car get to 220F and not even the 1st stage sensor grounded (195). I am suspecting a plugged rad at this point.
FYI went from electric front fan (that died) back to a clutch fan and did these tests without the clutch fan on. Incase you were wondering how I got the car to 220F.
