strange noise

im new to tacomas, so if this is normal just let me know. however, when im in neutral with the a/c on i hear almost like a motorboat from the motor. strange thing is that when i press the clutch, the noise goes away, and if i turn off the a/c the noise goes away.

thanks

It's the a/c, when you push in the clutch, you are taking torque away from the motor so it revs and sends it to the a/c condenser, hence the noise, no big deal.

 

thank you very much
