the blower resistor controls the fan speeds
The only way to transfer heat in a vacuum is through radiation. Heat transfer by convection and conduction require a medium, such as air or a solid, to transfer energy. In a vacuum, radiation is the only method by which heat can move.
The only form of heat transfer that can cross a vacuum is radiation. Radiation does not require a medium to transfer heat and can travel through the vacuum of space.
Radiation is a heat transfer that can occur in a vacuum because it does not rely on the presence of a medium to propagate. It is the transfer of heat through electromagnetic waves, such as infrared radiation.
The blower motor resistor module is ruined and need replacement. It can be found from below and behind the glove box. Tt may be hard to see, follow the wires to connection that is mounted to the blower unit by two small hex-head screws. I removed the glove box so I could access it easier than trying to go from the bottom in a confined position.
Conduction and convection cannot occur in a vacuum or in space because they both require a medium, such as a solid, liquid, or gas, for heat transfer to take place. In a vacuum or in space, heat can only be transferred through radiation, which does not require a medium.
Assuming that by "high," "low," and "medium" you are referring to HVAC blower fan speed and that this happens with heat as well as with AC: Replace the blower resistor. It's no good.
a bad blower motor resistor heat normally used on medium and high medium usually burns out those speeds first till only high is left normally located right back under glove box on heater box/core line usually 20-40$
If you are referring to the blower motor only working on the high speed setting, then the problem is the blower motor Resistor Pack is defective. Replace it. It can be the blower motor speed control switch but not likely.
When the fan is on high it does not run through the blower motor resistor. The low speeds don't work because the blower motor resistor is bad.
You most likely have a bad blower motor resister.......
Figured it out...the blend door actuator was not fully seated when I replaced it.
the resistor for the blower motor is busted blower works on high with out it
Blower motor speed resistor is partially burned out.
Most likely the Blower Motor Resistor.
There is a resistor near the blower that is bad, known cause is high speed only.
A blower motor that only works on high is normally caused by a defective Blower Motor Resistor Pack. DRL, do not have a clue.
from what i have read it is the blower motor resistor it goes bad and only lets the fan run on high google blower motor resistor and read on
