2002 TrailBlazer 4.2 Fan Clutch at 100%

This is a recording of a TrailBlazer Electro Viscous Fan Clutch being commanded to 100% with engine RPM at about 2000. The command is being sent by a custom button at bottom right of screen in Torque Pro which I have configured at 100% duty cycle for a 5 second duration. It can be seen and heard that engagement is fairly rapid but disengagement takes nearly a minute. Keep an eye on the desired fan speed vs actual fan speed.
