What is the buzzing noise coming from the ac when the fan is on
What is your question?
every time that I turn the ac air fan on there is a buzzing noise (the higher the fan speed the louder the buzzing).
What makes this problem better or worse?
its louder when the fan is on a higher speed
How long has your 2007 Toyota Highlander had this problem?

Hello, sounds like you could have debris where the blower motor is, inside the "cage" of blades of the fan. Leaves and other debris can get in there. If you access where your cabin air filter is, you may be able to get in there and clean some of it out. Or seek a tech near you to help.
If there is no debris, the fan itself could be noisy. But try for debris first.
I just saw your response thank you very much, I am sure this will help... Is the cabin air filter located in the rear of my glove compartment ?
