when i turn on the ac in my 2000 Honda civic it makes a loud noise when the fan is working what could that be ?
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.
There are a few things that might cause an air conditioner to make a rattling noise. It could be that the there is dirt and debris in the cabinet. If this is the case, cleaning the cabinet should stop the rattling. The reason could also be loose panels on the cabinets. The fan could also be bent and no longer straight.
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.
It needs replaced - bearings are out of it.
The rattling noise is in there so you can move the head around.
It is the fan blower for the engine cooling system (Radiator)
You will need to remove the fan and check for debris in it.
Maybe a bad bearing in fan motor
yes, the fan bearing is worn out
The screeching noise is most likely the blower motor. Either the motor itself is bad or the fan blades are striking the housing. Run the heat without defrost and see if the noise is the same. Also check at different fan speeds to see if the noise changes.
Dust from drywall cutting for example is fine enough to get into the blower fan motor and cause a squeaking noise. You'll need to replace the fan if this is the case.
it sounds like the compressor drive belt is loose under the hood.or the noise may be the blower motor{blower that pushes air into your car} rule blower motor out by using fan in heat mode. Or maybe a bearing in the clutch has gone out.
