How To Fit A Renault Scenic Heater Resistor?

How do you replace a blower motor resistor?

How to Replace a Blower Motor Resistor

  1. Remove the negative battery terminal.
  2. Locate the blower motor resistor on the passenger side under the dash board.
  3. Disconnect the electrical connector to the blower motor resistor.
  4. Remove the screws or bolts to the blower motor resistor and remove the resistor.

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.

What is a heater resistor?

The blower motor resistor is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed. A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system.

How do I know if my 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.

How much does it cost to replace a blower motor resistor?

The average cost for a Blower Motor Resistor Replacement is between $108 and $137 but can vary from car to car.

Where is resistor 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.

Can I bypass my blower motor resistor?

In the highest speed state, the blower resistor is bypassed completely and the fan is connected directly to the car’s battery, which allows maximum current through the motor. Power to the blower motor is fed through the blower motor resistor, so if it fails or has any issues power can be cut off to the motor.

How long does it take to replace a blower motor resistor?

takes about 45 minutes.

Can you fix a blower motor resistor?

The resistor module is easy and inexpensive to replace. It’s then typically installed in the ductwork, near the car blower—either under the dash or under the hood. (Refer to a service manual to locate yours.) Purchase a new resistor module at the auto parts store (usually less than $25).

What causes heater resistors to burn out?

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 are the signs of a bad blower motor relay?

If you have a faulty blower motor, you may experience low airflow from the vents, even when the fan is on high. There will be no air coming from the vents if your fan isn’t working due to a bad blower motor resistor.
