- Remove right lower instrument panel insulator panel.
- Disconnect blower resistor connector located behind right side of dash.
- Remove blower resistor screws and blower resistor.
How to troubleshoot a blower motor resistor?
How to Troubleshoot a Blower Motor Resistor Locate the fuse for the blower motor in the owners/service manual. Unplug the blower motor and test for power using the 12-volt test light in the same manner as explained in Step 1. Test for ground at the blower motor if there is power indicated at all ranges, but the motor does not function.

Can you repair a blower motor resistor?
The average cost to replace the blower motor resistor at a repair shop is between $44 and $55 in parts and $70 in labor costs, for a total cost of around $114 to $125. On the other hand, you can easily fix the blower motor resistor at home in about an hour (even if you're a beginner) and for around $70.Jul 14, 2021
Why does a blower motor need a resistor?
The blower motor resistor is responsible for controlling the blower motor speed. In the past, this was done by varying the voltage supplied to the blower motor. In newer applications, the blower motor resistor is actually a solid state module that sends a varied signal to the blower motor.
What happens when the blower motor resistor goes out?
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.Jan 8, 2016
How do I know if it's the blower motor or the resistor?
Typically, if the fan will work on some speeds but not on others, the resistor is suspect. Okay, let's say there's no melting going on, but your fan doesn't work on all speeds. Typically, if the fan will work on some speeds but not on others, the resistor is suspect.May 13, 2021
Does a blower motor resistor have a fuse?
A fuse is often located on the resistor board. The fuse only protects the low and medium blower speeds. High speed will still work if the resistor fuse is blown.
Why does my blower motor fuse keep blowing?
Blown fuses If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.Jan 4, 2016
Is a switch a resistor?
In short, a switch creates an open circuit and a resistor reduces the current in a closed circuit.Dec 17, 2019
Can you drive a car without a blower motor?
Your car's blower motor is not only necessary for the operation of your air conditioner. Without a functioning blower motor your engine runs the risk of overheating.
Is there a fuse for the blower motor?
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.
Can a bad blower motor resistor cause no heat?
Problems with Your Blower Motor or Blower Motor Resistor The blower motor resistor is the part that controls the fan speed of the blower motor. Both of these components can fail, resulting in the heating system simply not working.Dec 1, 2021
Can you get the dealer part back then?
Back then you could only get the expensive dealer part.
Do junkyard owners destroy parts?
Now, sometimes junkyard owners instruct their part puller employee to destroy a good part just to sell a more valuable part (but difference is, they own both parts).
