The resistors are there to give the blower different speeds. To get the blower to run a little slower part of the energy gets dumped into heating the resistor instead of spinning the blower blades.

Why does the heater fan in your 1992 Ford truck only work on high?
by the blower motor there is a resistor connection, you will find it melted the blower motor is bad. it draws to much power causing the connection to get hot and melt and burn. you will have to change the connector and the blower motor. the blower is still working but its drawing to much power, the motor windings are shorted out inside. disconnect the connector from the resistor and you will see it.
Can't change the air flow in my 2004 cavalier no matter what setting the switch is on?
Do you mean the blower motor? Need more info to answer. Could be a bad ground that is causing the fan switch to be hot all the time, or a blown blower motor resistor. Does it turn off when you turn it to the off position? If so and it only works on one setting, its the blower motor resistor.

Blower motor only runs on high and only blows hot?
You have 2 problems. First, the blower motor running only on the high speed is caused by a defective blower motor resistor pack. Replace it. Second the fact that it is only putting out hot air indicates the temperature control valve is defective or stuck.

Yes. Hot water comes from the water heater. The blower motor propels warm air around the house through the duct-work, but is not connected to the hot water heater in any way.
How do you fix the blower on your 1991 ford explorer so the ac blows cold air?
