blower motor is locked up either something inside cage is keeping it from turning or bearing is locked up and won't allow it to spin freely.
Motor is drawing to many amps through fuse because of resistance
check blower in glove box, there should bee a cabin air cleaner that can be taken out and see motor. if from year 02 and up. see if you can spin motor by hand, if not replace motor. if fan switch doesn't work on all speeds could be blower motor resistor needs to be replace, this could why motor heating up an blowing fuse.
The Dodge Durangos are known for blower motor problems. The blower motor is under the glove compartment/dash in the big black box, and so is the evaporator coil. There is a outside air filter that tends to wear out and break apart. Once this material breaks apart it ends up in the blower motor and can cause the motor to stop turning, or turn slower than normal. You will need to open the blower motor compartment under the dash and clean out any obstructions/trash and check the motor if it spins freely without much resistance. If it resists turning by hand or there is no trash and it still fails to work, you will need to replace this blower motor.
If the motor spins freely and there is no trash, you may just have a bad blower motor resistor or A/C control switch/panel.
Replace the blower motor resistor assembly. To locate the electrical connector for the blower motor resister, it is usually attached to a heating or air conditioning Duct, or the blower motor case. You can also trace the Purple Wire from the blower motor back to the resister. Also make sure that the blower fan is not jamed up with somthing in side and will spin freely,or binding same thing, this will also cause the fuse to blow right away. And does the motor actually spin a bit before it blows the fuse or does it blow the fuse at the same time the switch is turned on? Good Luck and have a good XMASS.
do all of the fan speeds work? if not you need to replace the blower motor resister. If all of the fan speeds work then you need to clean or replace your in cabin air filter. When this filter gets clogged you get very little air flow from your vents. Instructions for your cabin air filter service are in your owner's manual
blower motor location is in the heater box down by the passengers feet the fan relay in out under the hood in the power fuse box check this first
check to see if the blower motor turns you can do this by removing the three screws the motor and squiral cage will come out spin it if it moves freely putit back replace the switch assembly
Replace the blower motor resister,it is mounted right next to the blower motor,it has a lug with about 7 wires on it.Just unplug it and remove two screws to remove the resister.This controls the speeds for the blower motor.The blower motor is the cause of the resister failure.Even if the motor seems to sound,and run fine,it is pulling to many amps.
