Hi My car was making alot of noise when the Air Cond was on on startup and all the time. All of a sudden, the noise stopped, the air seemed to blow NOT as hard or cool, My temp sensor light went on and said to bring it in. I have looked up things on youtube etc. It says that my MAF sensor may be the culprit...or the ECM. But here is my question, the fan does not even go around easily by hand...is that normal. Any ideas what it could be before I dump a ton of money for something I could maybe do myself. I dont even know where the MAF is in this car.

Any advice?
