Extremely loud heater (vehicle, windshield, Dodge, noise)

[ashcody]

So this is probably a "stupid" question but I don't really know anything about cars. I turned on the heater in my car today only to hear it making an extremely loud noise...at first, i didn't know what it was but then turned heater up and the noise kept getting louder the higher the heat was on. What would be the issue and will it be expensive to replace? 2004 Dodge Stratus in case anyone needs to know. Sorry if it is a dumb question...but like I said, I know nothing of cars! Thanks in advance.

*Heater worked perfectly fine yesterday.

What kind of noise is it?

If it's a loud rushing air type sound there's a good chance you inadvertently switched the heater settings from outside air to recirculate.

It sounded like it was coming from the glovebox, it was like a clicking noise and just kept getting louder the higher i turned the heat settings up.

Just a guess on my part based on your description. Something may have fallen into one of your dash vents and gotten caught in the blower motor.

Depending on the make and model of your car the difficulty in getting to the blower can vary.

could be the blower starting to fail...

if you park under trees it could well be leaves have been drawn in near the motor fan. i have seen that several times over the years

If the clicking sound changes with the change of blower motor speed it could be any of what was mentioned above. Your vehicle is not old enough for it to have worn out blade shaft bearings. I don't know the tighness of the space it has around it but if the blower motor is loose, it could make a cyclic noise. It could easily be a piece of tree debris that can get sucked in through the cowl at the bottom of the windshield. As long as it is still working, use it.
