Honda heater makes loud noise

My honda heater heats up, but makes this terrible vibrating loud noise when I turn it on. At first I could run it on low, but now I can not even do that without the loud vibrating noise.

Ok well its possible there may be something stuck in the blower motor under the passenger side dash. ..or the blower motor itself could be on its way out, sometimes leaves or sticks from trees and even stove inside the glove box can find their way into the windshield cowling and into your blower motor..u can remove it to check by unplugging its white connector and remove the 8mm bolts that secure it into the heater core box..its very easy to remove..the 8mm bolts / screws should also have a phillips head on them...

Engine making loud noise when running I removed the serpentine belt and stop?

Turn all the pulleys by hand. Chances are you will be able to tell if there are bad bearings in cone of the following: Power steering pump, alternator, idler pulley, A/C compressor. The one that is failing will probably feel rough when you turn it or have a lot of play in it.

It very well could be the strut.
smaller chance could be the CV axle.

Makes a loud vibrating noise when heater is turned on

Is this an older vehicle? If it is the bushings in the heater motor are lacking lubercation or are worn out. On most cars the motor can not be lubercated so the motor will likely have to be changed.
