Where is the Alto fan relay located?

[StJesse]

The Alto fan relay is located in the fuse box in the engine compartment, which can be seen by opening the hood. A relay is an electrical control device, an automatic switching component with isolation function, which plays a role in automatic regulation, safety protection, and circuit conversion in the circuit. More related information is as follows: 1. A relay, also known as an electric relay, is an electronic control device. It has a control system (also called an input circuit) and a controlled system (also called an output circuit), and is usually used in automatic control circuits. In fact, it is an automatic switch that uses a smaller current to control a larger current. 2. Relays generally have sensing mechanisms that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); they also have actuators that can control the "on" and "off" of the controlled circuit; between the input and output parts of the relay, there is an intermediate mechanism that couples and isolates the input, processes functions, and drives the output part. The relay coil is represented by a rectangular frame symbol in the circuit. If the relay has two coils, two parallel rectangular frames are drawn. At the same time, the text symbol "J" of the relay is marked inside or beside the rectangular frame.
