AC making a fast chirping noise?
AC making a fast chirping noise? Yeah, "chirp". not sure how else to put it. but it gets faster if i increase the speed of the AC. it's like a really fast tick, not very loud but noticeable. my ac was working fine and now this noise. it still works fine, but the noise is annoying. am i low on r-134a or something?
increasing the speed of the ac - as in turning the **** up to the next speed. there are 4 speeds so the ac blows harder and colder. right?
blower motor? i guess it is that then, but why is it doing it? do i need to put that oil additive in my ac along with some r134a?
edit: it probably is that then. i just did some more research and that is most likely the problem since the noise is coming from the area where it sits. how do i access the blower motor? maybe there is just some junk in it and needs to be cleaned? is it easy to replace? i'm seeing them on ebay for cheap.

I've had leaves in mine before - don't know how in the world they got in there. Blower motor and fan cage come out as a unit from under the passenger side dash. Remove the electrical connector to the motor, remove 3 screws and it comes out as a unit. Definitely blower motor related if it makes the same sound with the AC turned off and fan on.
