Where is the heater blower resistor located?

Where is the heater blower resistor located?

The heater blower motor resistor is often found beneath the dashboard. It is located in the heater and air conditioning compartment. It’s connected to the air conditioning system, where it can adjust the speed of the blower motor fan.

Where is the blower motor located on a 2009 Honda Civic?

Note: The blower motor is located in the front passenger’s right side foot well area.

How do you know if your heater resistor is bad?

Symptoms of a bad heater blower motor resistor

  1. Fan does not work at all, so no air comes out of the vents.
  2. Fan only works on some speeds and not others.
  3. Fan only works on the highest speed.
  4. Fan runs all the time and can’t be controlled with the fan switch.
  5. You see smoke coming out of the vents.

What causes heater resistors to burn out?

In most cases, a blower motor resistor fails due to corrosion or overheating. Sometimes, the mechanical resistance to the motor rotation causes an excessive electric current that can overheat and prematurely damage the blower motor resistor.

How much is a blower motor for Honda Civic?

Honda Civic Blower Motor Replacement Cost Estimate. Labor costs are estimated between $54 and $68 while parts are priced between $139 and $142. This range is based on the number and age of Honda Civic’s on the road.

How do you test a blower motor resistor?

Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications.

Why does my heater resistor keeps blowing?

Trent, one of the biggest reasons for blower motor resistors to have shorten life is actually because of faulty blower motor drawing too many amps, some times melting wires/plugs, heating up resistors shortening their life.

What is a heater blower resistor?

The blower motor resistor is responsible for controlling the blower motor speed. The change in resistance controls the current through the blower motor, which in turn limits the speed that the blower motor spins at.

Can you bypass a resistor?

A wire in the left circuit is shorting the 100Ω resistor. All current will bypass the resistor and travel through the short. For analysis purposes, the 100Ω resistor can be removed.

Where is the fan resistor on a Honda?

To help everyone else, its in the Drivers side (RHD UK Model) just to the left and above the clutch pedal right up against the back. Looks like you’ve got to remove the entire centre of the dashboard to get good access to the fan motor. A pointer to a thread doing that would be appreciated.

Where to find the blower motor resistor for my AC heater?

Where do I find the blower motor resistor for my AC Heater motor. The motor stopped working without making any noise, it just died. I already checked all the fuses, and before I attempt to replace the motor I want to test the resistor, but I need to find it first. Any ideas please?

Why is my AC heater resistor not working?

I checked all the fuses of the under-hood and under-dash fuse boxes, and it just had burnt the number 12 (10A) and number 29 (20A). I changed them, but the blower motor did not work, and the Power transitor (resistor) did not heat. I changed the blower motor and the Power transistor (resistor) and they do not work.
