Where is the blower fan 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.
Does a 2008 Nissan Altima have a blower motor resistor?
This model does not have a blower motor resistor at the blower like previous models. Any ideas on the voltage readings or other possible issues would be appreciated.
How do you test a bad 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.
Where is the blower motor located on a 2008 Nissan Altima?
Blower motors are often found on the passenger side of the car underneath the dash. Inspect the blower motor resistor and the plug for melting, and check the blower motor fuse to ensure it is intact.
How do you know if your blower motor resistor is bad?
Symptoms of a bad heater blower motor resistor
- 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.
How do you troubleshoot a blower motor resistor?
This can be annoying, but troubleshooting is easy. If you start at the blower motor, and check resistance in the circuit, you will find the problem in no time. Power supplied from the fuse panel passes through the switch to the blower resistor assembly.
What are the symptoms of a bad heater motor resistor?
Symptoms of a Bad or Failing Heater Blower Motor Resistor. 1 1. Blower motor stuck on one speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower 2 2. Blower motor does not work on certain settings. 3 3. No air from the vehicle’s vents.
What does it mean if your blower motor is not working?
Average rating from 849 customers who received a AC is not working Inspection. 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.
Where does the power go in a blower motor?
For each higher speed, power flows through one less resistor. Some car makers run blower motor power through the fan speed switch first, then through the blower motor resistor and then to the blower motor and ground. Other car makers reverse that and run power to the blower motor first and terminate ground at the blower fan speed switch.
