After being turned on for some time my AC would make some whirling noise on the passenger side. When the fan is set low i can hear it and when I turn it off I can still hear it for some time over. Sounds like it sucking something out of a straw. Can anyone tell me if this is normal. Is it possible to have air pockets or something in the AC system. It didn't use to do that before. And also it would do it and I notice the AC isn't as cold either.

 

check your ac/radiator fan motor. the fan blades should spin freely with no play. if you feel it drag or wobble then the fan to the motor part is chunked. I ended up buying a new motor for 30$ at autozone

 

yeah just replaced both of them. still making that noise. The sound is coming from inside the cabin under the glove box.

 

prob the blower motor then. it's a pain to replace. gl

 

where is that at exactly again. How do you determine if the blower motor is bad
