On a 2007 Nissan Frontier, the blower motor resistor is typically located under the dashboard on the passenger side, near the blower motor itself. It is usually mounted to the HVAC housing. If the blower only works on high, the resistor may be faulty, as it controls the different blower speeds. To access it, you may need to remove a few panels or the glove compartment for better visibility.

The heater valve on an International 9900 truck is typically located in the engine compartment, near the firewall. It is connected to the heater hoses that run to the cab's heating system. To access it, you may need to remove some engine covers or components for better visibility. Always refer to the vehicle's service manual for specific details regarding your model.

Typically, a heater core has two hoses: the inlet and outlet. The inlet hose, which brings hot coolant from the engine, is usually connected to the top or side of the heater core. The outlet hose returns the cooler coolant back to the engine and is typically connected to the opposite side of the heater core. It's essential to check your vehicle's service manual for specific routing and connections, as configurations can vary by make and model.

A fan heater motor typically resembles a small, cylindrical or rectangular unit with a metal or plastic housing. It features a shaft with blades attached, which are responsible for circulating air.
