Hello,
Ive read through here and other sites and see this is a pretty common problem. My GFs cruiser has the rough idle problem when were sitting at a light or in park. You can hear the compressor come on when it does it. Also the more you drive it the weaker the ac blows and the warmer the air that comes out. I went to check the fan like I see people talk about and its not moving at all. Doesn't matter if its hot, cold or the AC is on or off. This car has 57k miles and its a 4 cyl non turbo car.

-So where should I start and what should I check?
-Anyone have a link to buy the radiator fan motor cheap?
-best way to replace the fan motor? Do I take the shroud off or what?
-AC probably needs coolant since I dont think its ever been charged and its only semi cool at stratup. Do I have to add oil separately? any recommendations on what brand to get? I have autozone and oriellys near me

thanks!
