2003 taurus no heat or a/c.
Thanks for choosing JustAnswer.
My name is Vladimir.
I have some questions, please reply in this thread:
1) You say there is no heat or A/C, does it mean that your blower motor does not work and does not blow any air through the vents?
2) Do you have a test light and can you read and understand wiring diagram?

1. thats correct.

Forgot to ask you if your A/C control is manual or it is an automatic climat control?
Customer: replied 8 years ago.
Both,I Think.
It could not be.
Does it look like this one( see the picture below) or it has three rotating knobs?graphic
Customer: replied 8 years ago.
Sorry, Yes what? as on the picture or three knobs?
Customer: replied 8 years ago.

As in the picture.


You have the electronic climate control ( EATC).
You said in your original question that you have found the blower motor.
Let's perform very simple test to verify if the motor is faulty.
Start the engine and set your climate control to vent and adjust the blower speed to high . Then strike the blower motor by hand several times in order to shake it.
If it starts working or tries to work, you will need to replace it. If this kick test does not help, remove the two wire connector from the blower motor and check if it gets power and ground. Just connect a test light or a +12 V bulb across those two wires ( orange and black). Your test light or bulb should glow.
If it glows, replace the blower motor.
If it does not, let me know and we will continue troubleshooting.
