Cooling Fan

WARNING: This page is about a different car, the 1995 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.

The PCM regulates operation of the electric cooling fan through the low fan and high fan control relays. Using information supplied by Cooling Fan Engine Coolant Temperature (ECTF) sensor, Engine Coolant Temperature (ECT) sensor, A/C signal and TP sensor, the PCM controls cooling fan operation by grounding and ungrounding relay circuits.
