Rattling Noise with A/C Fan?

I pretty sure the rattling comes from engine bay not from the fan below the filter housing but I will check it too.

Another thing is that rattling stops when I rev the engine a little bit.

Oh. you where told it is possibly a heat shield on your exhaust? If so then it might be a bracket that is cracked on the heat shield. That same thing occured to me several years ago on another vehicle. I just pulled the shield of and had it welded.

BTW, how many miles on your car?

The car has around 50.000 mileage now.

I went to a local toyota garage and they told me it could be the compressor but they are not sure as the rattling didn't happen when I was there. It is strange to blame compressor as the rattling stops when I rev the engine a bit

If the AC compressor is making noise it might not have enough refrigerant in the system. Do you ever have the AC serviced before?
