Lately I've been noticing a loud roaring sound coming from the engine compartment when my AC compressor is on. I noticed it the other night when my windshield fogged up, and I turned on the defroster.
I brought it by a shop today and they told me I needed an entire new fan module, which they said costs $410 bucks.
Needless to say, I want to get some other opinions. So I thought this was a logical place to do it.
If it's of any help, I posted a short video demonstrating the problem on youtube. You can view the clip by going here:
The noise is clearest at about the 40 second mark in the clip.
