the problem may be the blower control module.it is located under the hood by the blower motor itself,on the right side.it has a wirer connector plugged into it.remove batt connection.then remove module by removing the two small bolts.look at module one of the coil windings will be bad,if so replace module.
You will need to replace the blower motor control unit located inside the blower motor housing, this part is not the same as the part on standard explorers, it is not the same blower motor resistor.
Climate control blower motor was the fix. The part cost 441 dollars.
I had the same problem and ended up replacing the blower resistor and the blower motor. Although it could be one or the other .. mine was both.
What model? This probably has electronic Climate control,therefore there isn't a Blower resistor. The blower is controlled by a Blower Motor Module...its mounted on the HVAC case under the hood near/next to the blower motor.
Defective blower motor, blower motor resistor pack, or blower motor speed control switch.
Your blower motor relay went bad. You may also need to replace either the blower motor or one of the climate control sensors. If your blower motor squeals or makes a scraping sound it is going bad and will damage the blower motor relay. JQ
If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse.

your motor resister is bad or might be called the climate control module
Depends on the year. You could try the resistor first since it is the cheapest. If not that, then check the fuses, relays and wiring to the control head. Then lastly, change the motor.

Blower motor control relay under dash behind blower motor is bad or has water in it from cabin filter port.
If your blower motor is either not turning itself off, or randomly turning itself on with the ignition off (and you have auto climate control), the problem is the blower control module. Located directly behind the blower motor, it takes information from the climate control, and is in charge of turning the blower on/off. To replace the blower control module, remove the splash shield under the passenger side dash (there's 3 plastic retainers hold it in place). The blower control module is located behind the blower motor, and is held in with 3 bolts. The 2 rearmost bolts (by the firewall) only need to be loosened, and the front one removed. The entire unit rotates down and can then be replaced.
