Most likely you are correct that the blower is not working. Now we just need to find out why it is not working.

Here is a guide that will walk through the steps on this to get us started:

Below you will find the wiring diagram from the manual.

We need to start with checking voltage at the blower motor and then go back through the system until we find voltage.

Here is a guide that will help with this type of testing:

Please run through this diagram and let us know if you have questions on this.

Thanks

This is normally one of two things. Either the fuse/relay or the blower motor has failed. Here is a guide that will help figure this out:

I suspect you will find the blower motor is the most likely issue. Here is a guide that helps with this:

The blower is not working on the heater. It was working this morning but not now. Replace a/c compressor last October. How difficult is it to replace the blower?

When my car is running or when ever. I turn my air conditioning or heat on you can hear it come on, but it will not blow any air out the vents.

Good morning,

This sounds like either the blower motor or the resistor may be the issue.

https://www.2carpros.com/articles/low-or-no-air-flow-from-vents

Do you have a test light or voltmeter to do some testing?

https://www.2carpros.com/articles/how-to-check-wiring

https://www.2carpros.com/articles/how-to-use-a-test-light-circuit-tester

We will need to do some voltage tests to find the area of failure.

03 Taurus. Blower motor not working on any speed. Checked fuse, Good. Tapped on motor. It started to work although very slow even though fan was on high and had a grumbling sound. Turned key off and on again. Had to tap motor to get it running again. I have heard of issues with this vehicle having dampness on passenger side floor board and water in the motor. No water noticeable on floor board. Have not removed the motor yet. Possible bad motor?

Good morning.

I attached a wire diagram for you to view. Check the fuses with a test for power on both sides. There is a relay that needs power in order to let the blower motor work.

You can also check for voltage to the blower motor as well to see if the voltage is present which may indicate a bad blower motor.

The blower motor is under the right side of the dash.

My AC/Heater stopped blowing. Ive replaced the blower motor, the Blower Motor Relay and checked the Blower Motor Resistor and it looks to be ok. Ive also replaced the Blower Control Switch and still not working. The radio also stopped working the same day the blower did. Checked all the fuses and they are good. Not sure if that has anything to do with the blower?

My heater wasn't working about 6 months ago so my mechanic "fixed" it by blowing out the vents. This worked for about a month and now my heat, a.C, fan, defrost, & ect. Do not work. I'm thinking that it is an electrical problem of some sort but when I turn the knob to a different setting it seems to hiss, as if trying to work. Any help to what the problem could be or how to fix it would be gladly appreciated.

Underhood Power Distribution Box relay # 24 is for the blower motor

BLOWER MOTOR
Removal & Installation
Remove instrument panel insulator from instrument panel.
Unplug blower motor harness connector.
With key on and or engine running place the heater fan at high
check for power and ground and if you have them both suspect bad blower motor

Remove blower motor screws and blower motor.
To install, reverse removal procedure

blower motor job about $150 or so
good luck
