Help!! My 2000 ZX3 is making a weird clicking noise

I hope someone has an idea of what this is before i get really mad at my car again. When I'm driving and come to a stop at a light, the left side of my engine (or what ever is under the hood- I'm not car savvy at all) when your sitting in the car, is making this strange clicking sound. Last night it was the loudest its ever been, but generally it takes turning down the radio to hear it. I've been hearing the noise on and off since last week and now I'm hearing it more each time I drive.

I have no idea what is wrong with it- Can anyone please help me?
Thanks,

I had that same problem, but it only did it when my a/c was on and i took it in and they put a new a/c in and theres no noise anymore so you could try that !!

Either turn up the radio or open the hood and see where the noise is comming from. You have to narrow down the area. Have someone you trust that knows about cars help you.
