I am borrowing a 1998 3.8 manual Camaro to test drive and decide whether or not I want to buy it. It has 127k miles...but the engine sounds great. However, when I turn on the a/c, I hear a loud clicking noise which gets faster and louder when I rev or accelerate...then I turn off the a/c and it goes away. I was told its not uncommon for a Camaro (or any car) to make a clicking noise when the a/c is on. Although I get cold and hot air, this car makes a very loud noise. I have driven and ridden in a lot of cars with a/c and never noticed clicking quite so loud. Since I know almost nothing about cars, Im hoping this is normal...but if if its something to worry about, I want to find out before I put money into the car. Any suggestions?

 

my 96 was like that, it was the AC compressor

 

nothing to worry about, AC is basically the hemroid of the car, you dont really want it, and it can slow you down.

 

So is that clicking normal or something in the a/c that probably needs to be fixed/replaced?

 

i think mine was a loose pulley, the dealer fixed it for free

 

that clicking is ur ac in action, nothing to worry about, but im sure someone can quiet it for you.

 

Ok, thanks everyone!

 

The clicking is usually from the AC compressor clutch cycling in and out. If it does that at a rapid rate, it is a good chance that the refigerant is low. Try adding a can & see if makes less noise.
