There is no provisions for lubricating the blower fan bearings If it is making noise then the bearings are probably worn out and you have to be replaced the blower motor The blower motor is visable from the engine compartment It is on the firewall probably on the passenger side Remove the battery cable Remove the electrical connectors Remove the four screws holding the motor to the firewall Remove the blower motor It may be…
What causes a thumping coming from the blower housing on a 1993 Chevy Silverado when the ignition switch is turned on or turn off it lasts for about 30 seconds?
I would think that the bearings are going out in your blower motor. This motor runs any time the switch is on and as the bearing warms up the noise may go away but it will gradually get worse. I hope this helps you. Mark i bet its the blower vent door. try moving the lever to open and close it repeatedly before you start up the next time. tweek
You have two motors that benefit cooling, the condenser fan motor ( outdoors) and blower motor ( inside). Outside you may hear a noise, kind of like an out of balance noise). Inside, a little trickier. Noise may or may not be present, cooling quality decreases, ANC you may notice your filters may be staying cleaner longer. However, as with anything electronic, when it goes it goes..a tech can determine if motor is going bad…

What could a loud clicking noise in the side panel of the 3rd row seat of a 2004 Ford Expedition be when the rear air is turned on?
My 03 had the the same problem. Ford ended up having to replace the rear blower motor...it was still under warranty, thank god. If the air still blows then the blower motor is working. The sound you are hearing is a stripped gear on the flapper motor that operates the blend door. It causes the door to continually close and open. The replacement part costs about $35 from the dealer and is easy to replace…
A rumbling or humming noise with use of heat or AC that varuies with fan speed is usually caused by a blower motor that has a bad bearing. Replace the blower motor. Also, the next time you get the oil changed ask the mechanic to clear your AC evaporator drain tube and if you have a pile of leaves on your cowl, clean it off. If it's an irregular rattly type noise you may have…
Remove the trim panel under the glove box (one press in plastic stud and two plastic latches). You will see the bottom of the blower motor. The blower motor resistor is between the blower motor and the firewall. To replace it, first unplug the blower motor (connection on the firewall-side of the motor...note: press opening between leads to release wire connector). There are three screws that hold the blower motor in. They are equally spaced…
Is it a mechanical noise, or an air movement noise? If it's mechanical, it might be that the bearings in the fan or motor are dying. If it's more of a wind/blowing noise, it might be that you have a loose or broken heat delivery duct. If you stick your head under the dash, you might be able to hear and see where the problem lies.

That depends on where it's comming from, if it's an outside noise, it's probably a faulty mount and the motor is moving when it turns off. If it's an inside noise, it could be the ductwork flexes a little when the blower is running and "pops" back into place when the blower turns off. Finding the exact location of the noise will go a long way toward figuring out what's wrong. Check the filter? maybe…
99 Malibu at first the AC blower would only blow on high now not at all it also was making noise just before it died resistor or motor?
Why is your car making a grinding noise when you have the AC or heat on and you brake to slow the car and or give it gas?
Why do vacuum cleaners make the characteristic noise that they do - what type of engine motor causes this?
It is NOT the electric motor creating that sound, it is the suction pump that is driven by the motor that is creating that sound while creating the partial vacuum that sucks in the dirt. If you have an upright vacuum cleaner, the beater brushes also make quite a bit of noise when you have them turned on when doing carpets.
Loud knocking banging noise on 350 Chevrolet that comes and goes still drives when making noise but everytime accelerate it starts banging. noise is coming from the motor really hard banging.?
If the blower works on high speed, but not on any of the lower speeds, that usually means that the blower motor speed controller is bad. There is a resistor in there which can overheat and burn out. If the blower motor has a bad bearing (makes noise or doesn't turn as fast as it should) that would cause the system to draw more current than normal, and burn out the resistor. If that is…
