The resistor is located on the blower housing on the firewall under the hood under the relay center boxes.

SOURCE: Rear heat blows cold air

one of the second heater core lines is clogged.

Rule of thumb...unless you get a better answer:  look for a couple of wires on a small plate that is in the airflow of the fan on the heater/ac unit.  The resistor pack is always air cooled by the fan.

The Blower Motor Resistor is located behind the glove box on the dash. Remove the whole glove box to access. The Resistor is mounted against/sort of into the fire wall.
1. Disconnect the negative side of battery.
2. Disconnected the Electrical Connection to the Resistor.
3. Remove the bolts/screws. I believe they have 8mm heads, there should be 2 of them.
4. Replace with new one/Replug electrical connection.
5. Reconnect the negative side last.
6. Test System before putting the glove box back in!
The Blower Motor is easy (compared to $1000) to remove and replace.

in my 2004 grand caravan it's behind the glove box and left of the blower motor. disconnect the wires first then remove the 2 screws to pull out the resistor unit. First make sure you have removed the negative of your batterie. I had the same pm that prevented the blower motor to operate in any speed. I hope this will help
