I would like to test my heater blower motor how do i go about doing it?

That is the heater / AC blower motor ! There are electrical circuits and relays and blower motor resistor , blower motor etc... Electrical testing is the way to diagnose blower motor circuit . Looking at a wiring diagram to see what controls the blower motor on your particular vehicle would be the first step in diagnosing your problem . Do you know how to do automotive electrical testing , how to read or follow a wiring diagram ? Videos on youtube show how to test blower motor and related parts and wiring . Blower Motor and Resistor Diagnostics by Wells

if the blower is working when you jumper it at the motor you`ve eliminated the motor itself.if you have replaced the heater control with a new one or known good used one then the only thing is the blower motor resistor has gone bad.i`m surprised you did not check and replace this unit after jumping the blower motor.

Its located under dash,or near glove box.

The dash panel lower side has to be out.

HEATER BLOWER MOTOR

Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.

It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

First check the fuse for the blower motor in the fuse panel if it is blown replace it and see if blower works.If still not working you will need to buy a test light from your local auto parts store and check for voltage at the blower motor red wire if the test light shows voltage you might have a bad blower motor. There's a trick to test the motor called the tap test start the car and turn the heater fan on high using a mid size screw driver tap on the blower motor and see if it comes on if it does you need a new motor.

REMOVE HEATER BLOWER MOTOR HOT WIRE BLOWER MOTOR IT.IF IT WORKS.YOUR AC AND HEATER CONTROL SWITCH IS FAULTY.CHECK HVAC FUSES AND CHECK BLOWER MOTOR RELAY.IF BLOWER MOTOR DONT WORK WHEN HOT WIRE REPLACE IT.IF ALL CHECK OUT GOOD.HAVE DEALERSHIP DO A DIAGNOSTIC TEST ON YOUR CLIMATE CONTROL SYSTEM.

three things left to check,
using test light see if you have power at motor with key and switch on,if you do replace motor,if not locate blower motor resistor it will be close to motor,check for power going in,last is the heater control assembly

take a test light and check the wires going to blower motor, at least one should light up, if so replace blower motor sounds like it is bad
