    if wrong cabin air filter was installed could that have caused a problem in system? dealership says its normal to feel vibration after break in period. doesn't sound reasonable that its increasing.

Check the engine breather pipes for cracking and going soft first if they appear ok then its the idle control valve ?' a clean might do it

    they wear in ,what sort of lame excuse is that ??sorry havent answered earlier ,went out on my boat today fishing ,only thing i caught was a suntan ,Still it was the mediterain and this is spain and we all know what spanish fishing boats use -----flyscreen for fishing nets ---- ,Now as AC cuts in and out their is a slight drop but it should pick up more or less instantly and be hardly noticeable now the computer should sense the load and increase speed accordingly but this i think you will only find on more expensive cars like a VW but if you didnt get it before then it shouldnt do it now and 30k isnt a lot of mileage on a modern car ,OK i know it hasnt got a 5.7 litre gas guzzling engine but it shouldnt do it ,Now is their a reason for the compressor to be cutting in and out ?? even if its not that hot out unless it has climatic control.which will cut in and out .

The Air Conditioner in my 2004 Jeep Liberty gets warm while the jeep is in Idle. It has a new Radiator, new Condensor and the system has been charged. Any Idea what the problem could be?

If it only gets warm when vehicle is at idle. The problem probably is something to do with the compressor check to see if compressor runs with car at idle. I believe the problem is that when the vehicle is at idle the compressor doesn't kick on enough to keep the coolant circulation but when car is at speed the compressor runs correctly

Why am I experiencing intermittent vibration when I drive my new car.

A/C compressor kicks on and off, Engine cooling fans do to. This could be the vibration you feel. This is normal.

2010 ford fusion vibration at idle and acceleration.

Chances are its a minor miss in one of the cylinders. You don't feel it neutral at idle or until the trans goes into overdrive because those times the engine is not working very hard.
If it is a miss fire the check engine light will come on when it gets bad enough to affect fuel mileage.
If you have not yet changed the plugs I would start with that. There is also a chance you damaged the engine when it overheated.

My car makes a rattling/vibration noise - under the Hood when I am sitting idle at a light or parked (while running) - Only notice it happening when the Car cooling fan kicks on and my Air conditioner...

Airbox is not latched down properly. I had the exact same problem. I found the front of the airbox was clipped down but the back was bouncing up and down and making a racket at low idle. There are 2 clips on the front of the airbox and none on back. You have to put the rear of airbox down first and insert rear into the plastic slots to hold it. Then you put the front down and clip it down.

When stopped in drive the steering wheel vibrates a lot when the air conditioner is on .There are already new motor mounts replaced could it be the adjustment of the idle screw ?throttle plate cleaning...

The belt tensioner can cause many of these problems, sometimes the serpentine or fan belt is replaced, but the tensioner is not given much thought, a tensioner that is going out, can cause the belt to not have enough tension to keep the battery charged by slipping, when the clutch on the ac compressor cycles on and off, if the tensioner is to loose, or not tight enough can cause the compressor to vibrate, it can cause wear on other parts attached to the belt even cause pre-mature wear on other pulleys. good luck!

I have a brand new car and when the A/C is on and

You should feel a noticeable amount of vibration, although being a brand new vehicle it should not be too eccentric. Definitely not uncomfortable. If it is an uncomfortable amount, have the dealership replace the belt that drives the compressor, and if they claim your belt is plenty tight have them replace the compressor. The vibration could be cause by a loose belt that drives the A/C Compressor. If not, the compressor, itself, could be coming apart internally throwing off its balance as the internal parts spin.

Air conditioner knocks when turned on at low rpm

The a/c compressor has an internal failure .
Most likely will have to replace the compressor and recharge the system. The drier is also going to have to be replaced because the system was exposed to the out side air.
