Just bought back my 03 sonic blue GT coupe yesterday. Was cleaning the interior up today and noticed a clicking noise coming from the engine so I popped the hood and checked things out and notice the AC pulley is making a clicking noise it seems to engage and disengage every 30 seconds or so. Anybody have this issue? Will a freon charge fix things up? I will be taking it to my mechanic in a week once I get temp tags put on it.
