SOURCE: Inside fan switch has 4 speeds only high works,

I have great news!It is not that bad!Look near the blower motor in the blower case housing ther is a blower resistor.It will have a multi-wire plug in.Unplug this ,and remove the two screws that retain the resistor in the box.Pull the resistor out ward,it will be out.The part store will have it or can get it for you.This is your speeds for your blower motor.If the blower is making any kind of racket,or seems to be slow when it is on high selection,replace it also,cause this is the cause if the resistor going out.

SOURCE: My blower motor fan speed switch will work only on High.

I had a similar problem with my 03 Taurus. Does your floorboard on the passenger side get wet when it rains really hard? If so, Ford is aware of a defect above the fan motor which is behind the glovebox.
I contacted Ford directly and they had my local ford dealer fix it free and they gave me money towards a new blower motor which shorted out from the leak, it's possible it just your switch if there is no leak but you might need both the switch and blower motor replaced like I did. Hope this helps.

Try replacing relay for wiper with another same relay from fuse block from another working accessory.Had same issue on friends Ford Ranger. Moved relays and cleaned harness connection at fuse block. Works fine.

How do i fix the blower stuck on high


if it only goes on high, the resistor needs to be changed . It is on firewall ,passenger side of car under wiper assembly behind alternator. not a hard job to do, part is not expensive. you will get low,med , and high back. if not switch on dash panel, or change blower motor, last ,since it is going on- working. good luck

1992 ford ranger 3.0 v6 why does the air switch from low to high work only on high(blows on high only(


The part you need to replace is called a resistor tree. Usually found somewhere near the blower motor under the dash. This is a common problem on older cars.

Need to change fan motor control switch? Only works on high setting.


this problem is not caused by the switch, it is caused by a defective blower motor speed control resistor, the resistor is located near the blower motor.

the fan control balast (or speed controler) is burned out. by design if it only goes high, its junk. replace it and youll have it fixed. should be by the fan under the dash on the passenger side.
