Usually, with the information provided, it would probably be the heater control panel. The knob that you are turning, is the part in the system that is actually a "variable resistor", And as time passes, the contacts wear out, and eventually have contact in some areas, and none in others. The control panel is sold as a unit. And is pretty simple to replace. Anyone can do it with a common tool kit, and a repair manual. I hope that this is enough information, and saves you some greif, and money. Happy New Year.

Heater blower only works on high


Most likely the blower motor resistor or the fise for the low speeds. The high setting for the blower motor is on a separate circuit than the other lower settings.

Heater fan motoer only works on high setting?


many of the heater blowers use a resistor type switch to adjust the fan speeds, when the switch goes bad only the high speed will work. the resistor is usually located in the airflow in the heater box under the dash. find it , change it (it just plugs in) and it will work again

Why does my heater in my 2000 ford ranger only work on the high setting?


I assume that you are talking about the heater fan?

Your heater FAN has at least 3 settings, and for our purposes we will assume low,med and high

Low and medium run through a resistor High is wired direct
Either your resistor is bad or your fan is
I know it seems wrong that the fan could be shot but it could be pulling so many amps that it won't work in any other mode than high
I just had this happen on one of my trucks
Start with the fan

Blower motor for heater only works on high....what do you think I need to change. Relay or Resistor.


If the heater only works on the high setting, your problem is the heater fan resistor, not the relay.

Heater blower went out?


Either the blower went bad or the heater relay went bad. This does not sound like a heater core problem unless you where smelling a SWEET smell when it was running.

Heater only works on high setting


I'm assuming you mean the fan(blower) only works on high? If this is the case you have a bad blower motor resistor. It's easy to change. It'll be on the lower right of the blower box. Kind of behind the glove box.

The heater fan switch only works on the high setting


Generally this a problem with the blower resistor, but also check the fuse.

Heater only works on high


High/low fan relay. Locate relay location chart for location of relay, usually found at major auto parts stores such as Autozone, Advance or ORiley's.
