I had my blower motor quit on my '04 Town & Country. The Thermal fuse was blown in the resister block. All other fuses were OK.
I checked the amps load on the motor, requires an amp meter that will read at least 20 amps. Mine pulled 17 amps at start up and settled down at 15 amps.
Use an ohm meter across the fuse located in the middle of the resistors in the resister block. If blown, with the key off, connect an amp meter on each side of the thermal fuse, then with the fan selector on high turn the key on and read the meter. Be prepared to shut the key of quickly if the load exceeds 20 amps.
If you do not have an amp meter, then you probably should replace the motor as it is more than likey it is pulling to many amps.
The thermal fuse is a 20amp at 144*. I could not find that one but did find at Radio Shack a 10amp at 139*. I used 2 in parallel and replaced the fuse. Had to be carefull soldering in the thermal fuses. You will need to use a heat sink (forceps or small needle nose vise pliers) to keep the heat away from the fuses. Also the fuses will need to be positioned as near center in the middle of the risistors. I figured that the cost of the thermal fuses was at least a cheap try as the cost was $2 each. If they blow I will replace the motor. It has been a month and is still working.
You need to be carefull as the resistors will get hot if you run the motor.
