Re: Blower Motor Slowing and making noises
Well if the motor is making noise the wheel could be broken or possibly gotten something in the cage where the wheel is. If the speeds of the motor dont work on any setting but high the resistor is out

Check good voltage and ground for blower motor. Actuators under the dash may be restricting air flow? High speed doesn't usually use a resister.
Check for hvac trouble codes, in my part of the country, some of the national brand autostores will check codes for free, if there are any.
If you think problem with blower motor, itself, replace it. Sometimes, you can remove blower motor, use jumper wires for voltage and ground, using inline fuse, come off the battery, see if it blows like you think it should?
Are you referring to the blower motor inside the car? If so, they get leaves in them which puts them out of balance and makes them noisy. Just take out the blower, 3 screws, and clean it. That's the cheap answer. It can be a bad blower motor.
sounds like a mouse attack to me. mice get into the heater vents and blower motor cage and make nests. those can throw your blower motor out of balance, thus resulting in the noise and then the motor just gets jammed and stops operation. but it could be just the blower motor failure it self. have it checked.
Sounds to me like the A/C clutch is no good and out of adjustment.You should goto your nerrest junkyard and get a used assembly take the clutch off then you learn how it comes off and install it on yours the save the pump for later use if needed. The clutch should only have a .010 air gap after install between th inner elctro magnet and the clutch plate it's self.
It is probably the blower motor itself, does it change sounds or quit when operating the fan? possible debris is in fan cage, fan has a bad bearing, or a blade balancer slip on weight fell off. remove and inspect, possibly plug fan in when removed and check for operation,while fan is removed check housing compartment for debris or foreign material laying in the bottom, check fan blade for signs of rubbing contacts or broken fins
It's very possible that a mouse has gotten into the duct work and ended up trapped inside the blower motor fan. The now dead mouse would cause the blower fan to be out of balance & wobble considerably and make noise plus it would smell quite a bit. I see a handfull of dead mice in blower motor fans each year so it's not all that uncommon. The fix is to remove the blower motor and clean out all the debris. Most of the time the blower and fan are fine and can be reinstalled once they are cleaned up. Hope this helps you find your problem!
Most likely it does, if you can hit the motor and it will run. I can't say for sure but you might want to chk. to see if you got a heater blower motor resister. There located (if its got one) around the heater motor and it controls blower speeds, might be worth checking out.
