I have 2000 Honda CIVIC Ek3 (non VTEC). When AC ON there is an vibration in Idle RPM. Can feel the Steering wheel vibration at idle. When AC Off it reduces but still exists a bit. It increase with AC. I checked with my friends cars. Also Ek3. There was a little vibration. But vibration in my car feels more than that. How can I solve this.
Thank You in advance.

The AC pulley bearing may be bad or there's too much wear in the compressor. Compressors frequently need to be replaced every 100,000 miles.

Thank You very much,
Can't it be the engine mount or auto gearbox mount?

That would not be my guess on such a new Honda.
