A system for controlling operation of first and second electric fans is provided. The system includes a microcontroller that determines when first analog multiplexer is malfunctioning or a first channel of the first analog-to-digital converter is malfunctioning based on first values obtained from the first analog-to-digital converter. The first values are associated with at least one of a first speed signal associated with the first electric fan and a first driving voltage for the first electric fan that are received by the first analog multiplexer. The microcontroller modifies a control signal to induce the second electric fan to operate at a higher rotational speed when the first analog multiplexer is malfunctioning or the first channel of the first analog-to-digital converter is malfunctioning.
