Question about 2004 Dodge Grand Caravan
Using a test light, check for power at the blower motor connector. If thereis power there, replace the blower motor. If there is no power there, it could be the blower motor switch or the blower motor resistor. The most common is the blower motor resistor.

Hi, have you check your fuses and relays. If all is good then check the blower motor resistor, to see if you are getting power to it. If you are getting power to resistor,check and see if there is power at blower motor it self, if no power replace resistor. If you have power at blower motor replace blower motor.If you need more help just re post. Sorry i forgot all this is on passanger side of car inside might have to drop black kick panel.
Thanks dodge tec

Most likely is your blend door is faulty (bad motor/broken tab?).
Defrost is the idle possition ( as it is the most important).
You may have a disconnected vacuum hose from the climate controle panel if you recently (ever?) had work done in the dash area...
But my suspicion is the blend door motor...

Its common that the wire harness has melted where it connects to the blower motor resistor. To get to the blower resistor you must take off the modesty panel that
hides all the wiring. The right side of this panel (to the right of the
courtesy lamp) just swings out of the way on a plastic hinge, after you
untuck it from the other side. It does not come all the way off, but
it doesn't need to. After this, the other (larger) section removes with
three screws. (This panel must be reinstalled correctly, because
molded into it was part of the ductwork that routes air up to the
defrost vent on that side. Make note of how it fits before you take it
out.) Lay all this carefully aside where you can find them later,
especially the screws.
Once this is out of the way, the real fun begins. The blower motor is behind your glove box, partially obstructed by an electronic relay box (BCM). The blower motor relay is behind the blower motor, jammed up against the firewall. Disconnect the wiring harness from the resistor and the motor; tuck it out of the way. You should not have to take the blower motor out to get to the resistor, but if it's in your way, go ahead. Be careful to move your head out from under the dash...the blower motor is heavy, and if it falls on your forehead, you'll have an embarrassing mark to explain to people for about a month. The resistor mounts with two screws.
You can replace the resistor or just replace the wire harness if it's melted which is a common issues after a few years of being heated up from the electrical current running through the wires.
Good luck and keep us posted.
