My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Several reasons for a vibration with the ac on.First if there are any ac lines contacting the body or frame or engine where they shouldn't be if they are bent this causes this fault here.If you have worn engine mounts this can also cause this and if these are all o.k. the ac compressor starting to fail will cause this as well.All of these need checked into to pinpoint and repair the cause here.
Thanks Pete
