So when i turn my heater on, my belt or the pulley squeaks loudley, same thing for the airconditioner. When they are also on, the alternator says its not charging, anybody have any ideas, i want my heater, but not the noise. Thanks for any comments.

 

I would say your belt is loose,or needs to be replaced,you are just causing it to slip when you turn the heater,defrost on,then the alt is not spinning fast enough to charge.

 

that is alot of help, thank you very much
