Some of the service information for the 2016 CTS-V, ATS-V and Camaro refer to a fan controller but the controller is integral to the fan itself so the ECM is sending the control signal directly to the fan. No separate/serviceable controller exists as the DC brushless (BLDC) controller is built into the fan.
