Mine is now totally manual. It always runs when I turn the switch on, and it never runs when the switch is off. It is totally independent of the a/c. It's not really a good situation, but it's better than it not working at all. At least, now I am in control.

The cooling fan"expert" is here Probably, the low speed circuit has failed. Remove the 2 relays, key off. If you jump 3-5 on the green relay's socket,the fan should run low speed. Then jump 3-5 on the black high speed relay's socket the fan should run high. If the 2 speeds work, with strong airflow then the fan circuit/resistor is OK. (You could pull the ECT sensor plug, see if the fan comes on and stays on. That will set the CEL light.) The Pin 7 of low speed relay goes to PCM (Powertrain Control Module) which triggers the relay, and could be a wiring problem there. The a/c should trigger the fan after a short delay. Fan first, compressor next is how mine (V6) works. If the fan does not work, the a/c will overpressure shortly, turn a/c off asap. Here is a V6 schematic, the Zetec is the same, 1 fan motor instead.

The fans are wired in parallel. They should both operate at the same time at the same speed. Observe the splice designation (S44) on the drawing.

If only one works, the the other either has lost its power or the motor has failed.

I'd suspect the low speed dropping resistor is open. Check it with a meter.

I dont think buyin cooling fan would help since the one in it works fine its just not getting power from the slow speed circuit, lke it is from the high speed. I need to figuire out how to fix the slow speed circuit!!!! this car is getting frustrating!!!

It's always frustrating when you don't follow directions.

Test the resistor. Replace if open. Very common.
