One more thing...are you using the computer & IRCM to control the A/C clutch*? From the manual:
-=-
The electro-drive cooling fan system consists of a fan and a two-speed electric motor attached to a fan shroud located behind the radiator. The electro-drive cooling fan is wired to operate only when the ignition switch is in the RUN position, thereby preventing cooling fan operation after the ignition switch is turned to the OFF position.
WARNING: DISCONNECT THE COOLING FAN PRIOR TO PERFORMING ANY UNDERHOOD SERVICE SINCE THE FAN COULD CYCLE IF THE IGNITION SWITCH IS LEFT IN THE ON POSITION EVEN THOUGH THE ENGINE IS NOT RUNNING.
The cooling fan is controlled during vehicle operation by the integrated relay control assembly and EEC-IV module, which will energize the cooling fan under the following conditions:
• Cooling fan will run at low speed if:
a. Engine temperature is higher than desirable and fan has been operating at a low speed. Fan starts running at high speed at 110°C (230°F), and stops running at 107°C (224°F).
NOTE: Cooling fan will not cycle with A/C.
*The wide-open throttle (WOT) A/C cutout is used on all supercharged engine applications. During hard acceleration, a signal is sent to the ECA. The ECA then signals the integrated relay control assembly to cut off power to the A/C clutch field coil. This keeps the engine from being overloaded.

The cooling fan is controlled during vehicle operation by the integrated relay control assembly and EEC-IV module, which will energize the cooling fan under the following conditions:
• Cooling fan will run at low speed if:
- Engine temperature is higher than normal. Fan starts running at 106°C (222°F), and stops running at 101°C (214°F).
- A/C is on and vehicle speed does not provide enough natural airflow. Fan starts running at speeds at or below 69 km/h (43 mph) and stops running at 77 km/h (48 mph).
