Only one speed would most likely be the resistor or switch. The loud noises I cannot explain unless the motor itself is going bad or the mounting brackets have broken and its vibrating or further still.. somthing has gotten into teh blower motor.. leaf litter, a mouse, etc. ( scope it if you can). on a scope it should look like a SINE-WAVE ( fluid up and down motion kind of like a real wave) if however, you get a scattered, staggering line form, the motor is for sure bad.
One fan speed tells me its simply mechanical, the switch and or ressitor are not diffucult to change on most makes and models.... in hind site.. if you had lost the HIGH fan speed ONLY i would suspect the motor, ignore some of what i said :P

What is the purpose for the relay fuse for the blower in the 1993 Cadillac deville?
The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.
Blower will not blow fuse is good?
Defective blower motor, blower motor resistor pack, or blower motor speed control switch.
Your ac want blow how do you fix it?
If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.
99 sunfire heater only works on full speed?
1) Check the blower motor, make sure it is not making any weird noises.2) Check the blower motor resistor, its located next to the motor. It is what controls the lower speeds of the motor. You can try to find one at the junkyard.
What does the blower motor resistor do on a 2001 prism?
The resister for the 2001 prism blower motor drops voltage to the blower motor. This is how the blower motor runs at a lower speed.
Is a blower motor speed controller the same as blower motor resistor?
yes indeed
What does the blower resistor do in a 2006 Chevy Express?
The blower resistor controls the speeds of the blower motor Hi-resistance lower motor speed Lo-resistance higher motor speed
Your heater blower will just work on high speed?
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
Where is the blower motor relay on an 89 s10 blazer?
The blower motor high speed relay is located under the hood, on the passenger side firewall close to the blower motor. The blower motor speed resistor is also located in that same area.
What regulates the heater blower motor speed in an Isuzu Trooper 1999 and knowing where the blower the blower relay the switch and the blower fuse are located where are any other components?
there is a resistor that controls the speed and should be near the blower motor its called blower motor resistor
Where is the blower resistor located on a 97 cadillac?
Blower motor speed resistors are generally located close to the blower motor.
What list of things should you check on 2002 Chevy blazer before you replace the blower motor?
The fuse. The blower motor speed resistor. The blower motor relay. The blower motor switch. Check for power at the blower motor connection.
