Yes, It`s on the inside of the blower compartment cover panel.
To adjust the blower speed on your furnace, locate the blower motor and find the speed control switch or dial. Turn the switch or dial to the desired speed setting, typically indicated by numbers or labels such as "low," "medium," or "high." Make sure to consult your furnace's manual for specific instructions on adjusting the blower speed.
To change the blower speed on your furnace, locate the blower motor and adjust the speed settings on the control panel. This can usually be done by turning a dial or pressing buttons to increase or decrease the speed. Refer to the furnace manual for specific instructions on how to adjust the blower speed safely.
A fan or cooler relay is used in electrical furnace to change the blower speed to the blank speed for cooling
If you have a 2 stage furnace (hi fire & lo fire) then the blower will run on lo speed in lo fire & hi speed in hi fire and in AC mode. If it`s a single stage furnace lo speed for heat and hi speed for cooling.
In an electric furnace, a fan relay typically changes the blower speed to a lower setting for cooling. This reduced speed helps to circulate air more gently, allowing for better heat dissipation and preventing overheating of the furnace components. By operating at a lower speed, the blower can provide effective cooling while maintaining comfort in the surrounding space.
low
Can't give you a diagram but the blower speed resistor is under the hood, on the passenger side firewall not far from the blower motor in plain sight.

To properly wire the furnace blower motor for safe and efficient operation, follow these steps: Turn off the power to the furnace before starting any work. Identify the wires for the motor, typically labeled as high speed, medium speed, and low speed. Connect the corresponding wires from the motor to the appropriate terminals on the furnace control board. Make sure all connections are secure and properly insulated to prevent any electrical hazards. Test the motor to ensure it is running smoothly and efficiently before closing up the furnace. If you are unsure about the wiring process, it is recommended to consult a professional HVAC technician for assistance.
It depends on the duct system. Each furnace has a recommended outlet temperature. To get the proper airflow for that temperature the duct system has to be properly designed. If properly designed the speed would typically be low.
The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
