When does the cooling fan resistor come on?
The resistor controls when the cooling fan comes on, and normally it comes on in stages. When you turn your vehicle on, the engine heats up very fast so the cooling fan resistor comes on in stages. This helps to evenly cool your engine and allow your vehicle to run smoothly.
How does a belt drive Fan Fan resistor work?
A belt drive fan is mounted on a clutch that is temperature controlled, and the cooling fan resistor draws air through once the temperature is registered as too hot. The resistor controls when the cooling fan comes on, and normally it comes on in stages.
What are the components of a fan regulator?
Power loss unnecessary by heat. In the Triac based electronic fan regulator circuit there are mainly three components used. Resistor, One Capacitor, One Diac, And One Triac. TRIAC is a semiconductor device belonging to the family of thyristors. This is directly used to control the speed by holding and releasing the current flow.
How is a fan connected to a PWM generator?
Here are two diagrams who shows how I connected fan to PWM generator and power supply in two ways: 1. This diagram connected by this theory ( GND = Ground; VCC = +12; O / P = Sense /Tacho; VM = PWM) 2. This diagram connected by this theory ( GND = Ground; VM = +12; O / P = Sense /Tacho; VCC = PWM)
When to replace AC fan speed resistor 98-04?
Buy Now! When your blower motor for the AC and heat isnt working on all settings then chances are your blower motor resistor has failed. This is usually do to moisture from the cabin air box corroding the electrical component. Here we’ll show you how to repair it and if you’re in need of a new one, check out 1AAuto.com.

What are the symptoms of a bad cooling fan resistor?
Another symptom of a potential problem with the cooling fan resistor is cooling fans that stay on at all times. If the resistor shorts or fails, it can cause the cooling fans to stay on even when they are not supposed to.
What is the function of a cooling fan resistor?
This is made possible by routing their power through the cooling fan resistor. The cooling fan resistor is an electrical resistor that limits power to the fan in steps, so that the fan can operate at different speeds according to the cooling system’s demands.
