Best Answer

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.

Why does the blower only blow on high in your truck?

The good news is that it's not the most expensive part...the heater fan motor. You didn't say the year of your truck so I'll mention both the fuse and the resister. On some older models the low and high fans are on different fuses with the low fan fuse being an in line fuse. There is a resistor usually located under the hood near the heater motor that will also cause the problem.
