LD9 fan not working
 

So I solved my noise. It was a combination of bad alternator (died yesterday) and the compressor pulley/clutch.

Now in addition I have noticed now that the cooling fan does not come on at all, hence no A/C. Its pouring rain now but tomorrow I will check the fuse but that seems too simple. I assume it's just one relay to control the fan? Anyone have any issues with that in the past? I don't have a repair manual yet for the car so sorry if questions seem basic. I will test the fans off the battery but I don't think they are culprit. Lastly, where is the coolant temp sensor and how is it replaced?

And also, where do you guys go for parts? GM dealer?

On my 2002 there are two fuses (8-30A and 52-15A)and three relays (12, 14, and 15) for the two cooling fans and high/low mode. All are under the hood.
