Front blower motor for heat/air not turning on ?

there are 2 wires going to the blower motor.

the green wire should have 12 volts when the key is on.

the blue/yellow wire should have a good ground when the fan speed switch is set to HIGH.

Let me know which one you are missing.

I have an 2003 Durango also, and the same thing just happened to me. Cannot get the fan to go at all. So hope someone figures this one out.

You will have to do some testing.

Each situation is going to be different.
I can help guide you, but there is no magic answer.
