Where is the blower motor under the hood?
Where is the blower motor under the hood?
If you cannot find the blower motor under the hood it will be located under the dash on the passenger side. You may need to remove the mounting screws of the lower panel to gain access to the motor for removal. This heater motor location is under the dash. Let’s start the removal which is the same for under hood or dash applications.
Where is the resistor on a blower motor?
The location of this resistor is usually near the blower motor itself which cools the unit when it’s in operation. Both of these parts are located in the heater plenum box either inside the vehicle on the passenger side or under the hood mounted near the firewall on the passenger side.
What kind of motor does a blower fan use?
A blower motor is a basic 12 volt (DC) medium size electric motor that pulls a respectable amount of amperage (about 15 amps) which in time can burn out and stop working. As the blower motor ages the amperage that it takes to run the motor increases that overloads the electrical system which can cause additional problems.
What is the running amperage of a blower?
Assume that when the technician measured the pulleys and obtained the motor information, that a motor running amperage measurement was taken. This amperage is for the original conditions with a motor pulley of 8″, a blower rpm of 875, and the 3000 cfm airflow rate. The running amperage under those conditions was found to be 16 amps.

Where to test a blower motor in a car?
Both of these parts are located in the heater plenum box either inside the vehicle on the passenger side or under the hood mounted near the firewall on the passenger side. Use a grounded test light and locate the outgoing wire from the resistor to the blower motor (usually orange or red). While moving the switch to each fan speed test for power.
What happens if you have a bad blower motor?
The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air.
How to test an automotive blower fan motor?
Blower Fan Works on High Only 1 Locate the Resistor The location of this resistor is usually near the blower motor itself which cools the unit when it’s in operation. 2 Test the Resistor Use a grounded test light and locate the outgoing wire from the resistor to the blower motor (usually orange or red). 3 Replace the Resistor
What happens when a blower motor relay wears out?
Without it, the AC system will not be able to circulate any heated or cooled air. The blower motor relay controls the current used to power the blower motor, and is subject to the constant on and off switching. Over time, it can eventually wear out.
Why is my blower motor not working properly?
This is a classic blower motor resistor problem which is common on older cars and trucks that use manual fan speed switch controls. This problem will also occur on climate control systems when the speed controller has burned out omitting full power to the blower motor. This can also occur with the ignition key off.
How do you remove a motor from a blower fan?
While holding the blower motor in place remove the last screw. After all of the screws have been undone grasp the motor and remove it from the housing. This can take some maneuvering so hang in there and be careful not to damage the fan blade (squirrel cage) against the heater plenum.
