The blower resistor is in
the plenum right next to the blower motor
. It is held in by 2 screws and has a 4-wire connector. OK, so its located to the bottom right of the blower motor.
Where is the blower motor resistor located at?
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.
Where is the blower motor resistor located on a 2000 Ford Explorer?
The main climate control blower motor resistor is located
behind the glove box
. Lower the glove box, remove screws from 4×4 module and position it out of the way and that should gain you access to the resistor.
How do I know if my blower motor resistor is bad or blower motor?
- Fan does not work at all, so no air comes out of the vents.
- Fan only works on some speeds and not others.
- Fan only works on the highest speed.
- Fan runs all the time and can't be controlled with the fan switch.
- You see smoke coming out of the vents.
What happens when a blower motor resistor goes bad?
If the resistor shorts or fails,
it may cause the blower motor to remain stuck on one fan speed
. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.
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.
How much does it cost to fix 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.
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).
How do I know if my blower motor resistor is bad?
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.
What can cause a blower motor to stop working?
In a situation where the motor doesn't work on any speed, the most likely causes are:
a blown power supply fuse
, a bad motor ground connection, bad motor speed control module or a failed motor. On all systems, a failed blower motor is least likely.
Can you test a blower motor resistor?
If you want to do a quick test of the blower resistor, you can check the resistance of each of the resistors with a
multimeter
as follows: set the tool to read ohms (a measurement of resistance) and connect one of its probes to the common output terminal of the resistor.
Is there a fuse for the blower motor?
If the fan doesn't work, before pointing the finger at the blower motor, check fuses for the motor to make sure they're still good.
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.
What does a bad blower motor sound like?
You might hear this as a noise coming from directly behind the vent, perhaps
a light slapping
, or a sudden pop before you notice a problem with airflow. Whirring noises might also result from a bad bearing in the motor. … This is a telltale sign of a bad blower motor.
How do you test a bad blower motor 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.
How much is a blower motor relay?
Blower Motor Relay Replacement Cost – RepairPal Estimate. Labor costs are
estimated between $37 and $46 while parts are priced at $37
. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
