If the heater blower has humming noise when motor is running, first check its capacitor. If the capacitor is fine, then the motor is the problem and may need to be replaced.
Probably the heater blower motor.
its your squirl cage inside of your blower motor. guaranteed. happened to me twice
yes, the fan bearing is worn out
possible rear heater blower wheel has broken center hub!
The blower motor may be failing or there could be debris caught in the fan.
Change the blower fan speeds to see if the noise changes. It is possible that the fan is still running while the heat is off, and the fan is rubbing.
Yes, it's not how to reduce roots blower noise level, it's how to reduce turbo blower noise level. Normally turbo blower noise level is less than 80 dba when roots blower noise level is more than 90 dba, some user are still not satisfied, they want the noise level below 60 dba or even 50 dba. Turbo blower ZCJSD has it's own suggestion to reduct turbo blower noise level: Wrap the outlet pipe with sound-absorbent material， please see below photo:
HVAC blower motor going bad could make a rumbling noise in the car near the glove box
If the noise is a squeaking sound, it could be coming from the bearings in the blower fan. It could also be coming from a worn bushing or bearing in the blower motor.
it possible is the blower motor is going bad or the blower motor squirl cage is rubbing Most likely there is debri in the blower motor cage, usually mice get in there.
I assume you mean "heater". And a sudden failure is probably just the motor going bad.
depends what type of engine you have, on a 3.3L you have to remove the steering pump before you will be able to completely remove the blower motor; on the 3.1L you have to remove the alternator before replacing the blower motor
a mouse has built a nest in the the blower cage
The bearings are out of it. Replace Blower motor.
As for why it blows only on the high speed you most likely will have a bad blower resister and for the noise, it could be a bad blower motor, bad blower wheel or trash that is stuck in the blower wheel or housing.......
it might be that the moter on the fan is starting to go. i have had that noise on two different vehicles and it was the blower motor. and it went with in 6 months to a year.
You have a bad Blower Control Module. It is located on top of the HVAC plenum under the Maxi-fuse bracket at the firewall.
If it's a grinding or howling sound, the heater blower motor bearing has probably dried up and ready to fail.
A squeaking noise coming from the glove box on a 2003 Dodge Ram might be the heater blower fan. Try oiling the fan to see if it will stop. It could also mean that a screw is missing from the dash and the squeaking noise is the dash moving a little in that area.
I take leaves and twigs out of the heater blower motor fan by remove four screws from a plastic housing under the glove compartment. The motor falls into your hands. PS the leaves and twigs make a heck of a noise - when you put the fan motor on.
if it's a e-250 take the battery out and remove the three screws holding the blower,remove the wire harness,remove drain discharge tube,lift blower out of cavity and re-install with new blower motor.re-connect wiring harness and drain,tighten screws making sure the blower is installed in the correct position.install battery with tie-down holder for battery tray. check blower,by turning the blower switch to low then medium,and hi.listenn for noise or cage hitting frame. If ok..your done.
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.

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 stuck fast to the firewall and you will have to pry it loose
one of two things either your heater core or your blower fan
