Reason I ask is maybe the valve that controls the speed of the fan is somewhat sticking and doesn't respond very well to slight increases in speed but when you pull the connector for the ECT its enough to force it to full speed.

May be pulling the connector a few times and stroking the proportional valve on the hyd fan will allow it to operate freely again.

Or your just low on referigant...........

I think I am low on refrigerant, pretty sure that's why the AC is crappy. I know the computer uses all that info to decide fan speed. Do you think low refrigerant will affect it's decision?

I agree that getting my fan to go to WAIL mode to free up the solenoid is a good idea. I was thinking the same thing.

SO, just to make sure, the ECT (??) that's the sensor on top of the motor right between the AC and the alternator...? Engine Coolant Temperature Sensor, right?

My brain feels a little slow today...
