2012 jeep libery blower motor control processor location

Processor? This system consists of a control unit ( switch/selectors ) a blower motor resistor and a blower relay. If the blower fan is not working on all speeds, suspect a resistor ( common problem ). If the fan is inoperable, possible fan motor,fuse,relay,wiring and in some cases the resistor as well. The resistor is located under the passenger side dash area close to the heater motor. The wiring coming from the heater motor will plug into the resistor

if the lower fan speeds dont work but the fastest speed does the heater fan resistor block needs replacing. If the highest fan speed doesnt work leave it on there and check for power at heater blower fan, if power is on one wire and the other is an earth the blower motor fan needs replacing. Use a normal globe test light to check this. If no power on any wires to fan go back and check all fuses in car and under bonnet with same test light. If fuses are ok possible open circuit wire to fan.

Problem with a/c and heater fan, will only work on high 03 ford escape

This is a common issue with most vehicles. The blower motor uses a resistor to control the fan speeds. Once the resisters burn out, making them inoperable, it will only work on high position. The saftey is that it will work on high only, so the vehicle will have some type of air movement, and then the heater/cooling control can be used. Craig

There should be a relay that provides power supply for the fans.
If the fans only work on high speed, the fans are not faulty.
The most likely cause is a faulty fan speed control resistor module.
The resistor module is usually located in the blower fan ducting, in the fan air flow. It is typically a plugin unit, affixed to the ducting with a couple of screws.
