Your 2014 Nissan Rogue blower motor has stopped working, and you’re considering taking it to the dealer. But first, you want to try to fix the issue yourself.
In this post, I’ll explain the reasons your blower motor might not be working. You’ll also learn how to fix the issue yourself. Let’s dive in.
Causes of Blower Motor Issues in the 2014 Nissan Rogue
One common cause of faulty blower motors in 2014 Nissan Rogue cars is a blown fuse.
When a fuse gets blown in your car, the vehicle may get a short circuit. As a result, all the electronic devices in the vehicle, including the blower motor, will not receive adequate power supply. Your blower motor can’t work without sufficient electricity.
To fix this issue, you’ll need to find and replace the blown fuse. You can tell that a fuse is blown if the metal strip at the center is broken.
Another reason why your 2014 Nissan Rogue blower motor may stop working is a bad relay.
Your blower doesn’t turn on immediately after you’ve switched on your AC. This is because the blower motor requires a large amount of electrical current to operate. If the motor sources all the power it needs immediately after the AC is on, the system might become damaged.
To remedy this situation, the blower motor relies on a relay to activate it after the AC is powered on.
As time passes, your blower motor may become faulty and eventually stop working. If the relay is dead, the blower motor won’t turn on.
You can solve this problem by changing the blower motor relay.
Faulty Blower Motor Resistor
A faulty blower motor resistor can also prevent your 2014 Nissan Rogue blower motor from working.
Your blower motor resistor controls the speed of the blower motor by matching it to the speed of your fan.
Like other components in your vehicle, this resistor can develop issues after a while. When this happens, your blower motor may turn on, but it won’t move at all.
You can tell that your blower motor resistor is bad by testing it with a multimeter. To do this, you’ll need to insert the probes on the resistor into the multimeter. If the voltage reading on the multimeter is more or less than 12 volts, your resistor has gone bad.
You’ll need to replace the resistor in your car to resolve this issue.
Your blower motor might fail to work because its wires are broken.
When it rains, water may leak into your vehicle and corrode the wires on your blower motor. Rusty wires won’t deliver sufficient electrical current to the motor. Without adequate electricity, your blower motor won’t work.
Check your blower motor’s wires for signs of rust. If the wires look rusty, you’ll need to change the connector on the device.
Bad Blower Motor
Sometimes, your blower motor may go bad even when other parts of the AC are working perfectly. This just means that the motor is due for a replacement.
But don’t replace the motor without confirming that the device is bad. To check if your blower motor is dead, connect the probes on the motor’s resistor to a multimeter. If the voltage reads 12 volts when the motor isn’t working, chances are the blower motor is faulty.
A more effective way to test your blower motor is to link the motor to a 12-volt battery using an alligator test cable. If the blower motor doesn’t spin after you’ve successfully connected it to the battery, the device is dead. In that case, you’ll need to replace your blower motor.
Faulty Climate Control Unit
A bad climate control unit might seem like the most unlikely reason for an inactive blower motor. However, it can also prevent your blower motor from working.
Here’s why it’s possible: Your blower resistor needs to know the fan’s speed before it sets the blower motor’s pace. The resistor receives this information from the climate control unit.
If the climate control unit is faulty, it might suggest that the fan is off when it is actually working properly. This will make the blower motor’s resistor keep the motor off.
You can solve this problem by changing your climate control unit.
How to Fix 2014 Nissan Rogue Blower Motor Problems
Change Blown Fuses
Changing the blown fuses in your 2014 Nissan Rogue can fix your faulty blower motor. You can tell that a fuse is blown if it’s broken at the center.
In most cases, the fuse that affects your blower motor is located under your dashboard. This fuse could have a 20-, 25-, or 30-amp rating.
Inspect all the fuses under your dashboard first. If none of them seems blown, check the fuses in the fuse box below your hood.
If your blower motor doesn’t work after you’ve changed the blown fuses, try the next tip.
Replace Your Blower Motor Relay
Another way to repair your bad blower motor is to replace the motor’s relay.
Use your owner’s manual to identify the relay. Then search for the relay in the fuse panel underneath your hood. Also, check the fuse box below your dashboard.
Once you find the relay, replace it.
Is your blower motor working now? If not, continue to the next step.
Replace Your Blower Motor Resistor
You can also try fixing your blower motor by replacing the motor’s resistor. You’ll find your blower motor resistor behind the pedal assembly underneath your dashboard.
Follow these steps to replace the blower motor resistor in your 2014 Nissan Rogue:
- First, remove the instrument cluster on your dashboard.
- This will help you access the mounting screws on the bracket connected to the pedal assembly.
- Once you’ve pulled out your instrument cluster, you’ll notice a hole in the dashboard.
- Look into the hole to find the screws on the bracket. Then use a 10-mm socket to remove the nuts on the bracket.
- Next, detach the pedal assembly from your car.
- This should reveal your blower motor resistor.
- Take out the screws on the resistor to release it from your car.
- Now, get the new blower motor resistor in.
When you turn your AC back on, the blower motor should be working. However, if the device isn’t working, continue to the next step.
Change the Connector on Your Blower Motor
A bad wire is a common culprit for faulty blower motors in the 2014 Nissan Rogue. This is why replacing the connector can fix the issue in your blower motor.
Here’s how to replace the connector on your 2014 Nissan Rogue blower motor:
- Cut off the connector on your blower motor.
- Make sure to cut close to the edge of the connector.
- Get the new connector.
- If the wires on the new connector are too long, break off a small piece.
- You need to have enough exposed wires to attach the new connector to your blower motor.
- Use a wire stripper to remove some insulation from the connector and blower motor wires. Then twist both wires together.
- Finally, solder the twisted wires with a soldering iron.
After attaching a new connector to your blower motor, check if the motor is working. If the device fails to work, try the next tip.
Change Your Blower Motor
Not all problems in a blower motor are caused by other AC components. Sometimes, the blower motor in your car may stop working just because it is dead. In that case, you’ll need to replace the blower motor.
The blower motor in your 2014 Nissan Rogue is located behind the pedal assembly.
Follow these steps to replace the blower motor in your 2014 Nissan Rogue:
- First, detach your instrument panel from the car.
- You’ll find a hole behind the panel.
- Look into the hole. Then search for the mounting screw on the bracket linking your pedal assembly to the dashboard.
- Remove the screws with a 10mm socket.
- Take out the pedal assembly. Next, remove your blend door actuator.
- You should see your blower motor now.
- Detach your blower motor.
- Get the new blower motor and install it on your dashboard. Then re-attach all the parts you’ve removed back to your vehicle.
