2000 Honda Civic Heater Fan Not Working


Jun 8, 2022

What causes a heater fan to stop working?

If little air is coming through the vents (hot or cold), then it could be because the blower motor for the fan or a switch or resistor that controls fan speed isn’t working. Another cause might be that the electronically controlled “blend doors” that direct air flow are stuck or broken. via

Is there a fuse that controls the blower motor?

Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. The blower motor is usually under the dashboard on the passenger side. via

Is there a fuse for blower fan?

Fuse Protection

To protect the blower motor power circuit, a 20-, 25- or 30-amp fuse is usually located in the fuse panel under the dash. The rating of the fuse will depend on the vehicle application and how much power the blower motor requires at full speed. via

Where is the fuse for the heater blower motor?

Locate the reset button on the furnace and press it to reset the furnace. It is usually located inside the blower compartment on the side of the blower motor. Be cautious as the housing may be hot. If the button is popped up, press it down. via

How do you tell if it’s the blower motor or resistor is bad?

A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. via

Can a blown fuse cause heater not to work?

If a new fuse blows as soon as the blower is turned on, the heater circuit or motor may have a short that should be investigated. If the fuse lasts a while and then blows, the fan motor is probably running hot due to worn brushes and/or bushings and should be replaced. via

How do I know if my heater fuse is blown?

You can quickly determine by checking resistance with a multimeter. A good fuse will have nearly zero ohms of resistance, if the fuse is blown there will be no reading. via

What relay controls the blower motor?

In a blower motor, the relay supplies the power that allows the fans to circulate warmed air. Essentially an on/off switch, the blower motor relay’s reactions start and end the heating process in HVAC systems by controlling the flow of current between the power source and the motor. via

Where is the fan control relay located?

The fan relay is usually located near the bottom of the engine compartment on a metal frame member. The metal acts as a heat sink to keep the fan relay cool. So, unplug the connector at the relay and repeat the check for power. If you get power, you’ve got a bum relay. via

How do you check a blower motor fuse?

  • Use voltmeter or ohmmeter to check for a blown fuse.
  • Start car and see if blower motor works.

    How do I know if my heater core is plugged?

  • Weak or no airflow.
  • Cold air (not warm) coming through the vents when the heater is on.
  • Coolant leakage visible inside the cabin or a damp smell.
  • via

    Why is there no air blowing in my car?

    There are several possible reasons why no air is coming out of the vents in your car. Some of the most common causes include a clogged air intake, a blown fuse in the ventilation system, broken belts, clogged ducts, or electrical issues with the relay. via

    When I turn on my heat in my car nothing happens?

    A car heater that’s not working can be caused by the following issues: Failing or blown blower motor. Failing or blown blower motor resistor or blower motor resistor module. Bad or blown blower motor fuse, connector, or wiring. via

    Does heater fan have fuse?

    The blower motor is powered by a fuse-like device called a relay. If your heater or air conditioner does not blow air through the vents, this could indicate that the blower motor fuse has probably blown. While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle. via

    How much does it cost to fix a car heater blower?

    “A new car blower motor costs about $50 to $100 for the part and $80 to $100 in labor. Add it up and you’re looking at a total charge of $130 to $200 for a new car blower motor. via

    How do you check a heater fuse?

    You can test the fuse panel for power using the electrode tips of a voltage-amperage tester to verify that the power is off. Finally, you can move on to checking the fuses for potential damage. Depending on your unit, there may be more than one fuse in this box. via

    What happens if my blower motor relay is bad?

    If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system. via

    How do I test a blower fan relay?

    Connect a test light or multimeter to the ground (black lead). Turn the ignition key to the on position (engine off), and remove the relay. Using the probe, test all terminal sockets in the relay connector. Two of the four should have power. via

    Where is the blower motor switch located?

    It’s located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor. via
