Is the blue wire positive that runs the electric cooling motor?

The color coding of wires, including blue wires, can vary depending on the manufacturer and the specific application. In many automotive or electrical systems, a blue wire may be used for various functions, but it's not universally designated as positive. To determine whether the blue wire is positive for the electric cooling motor, consult the vehicle's wiring diagram or service manual for accurate information. Always exercise caution and ensure proper identification before making electrical connections.
