I have an 02 GT and have a question about when I have my AC now. I know you normally have that clicking noise from under the hood due to the compressor when the AC is on. I happened to have my hood open the other day when the AC was on and saw a movement that I'm not positive if it should be working this way. When your looking at the engine belt and the pully's that are moving it, everytime you get that clicking noise with the AC on, one of the pully's moves slightly like a pulsing move. I've never looked at any other engines when its on so I dont know if it should be moving like that. Thanks.
