Cause of a loud grinding noise when AC turned on

When I turn on the AC, a low grinding noise starts, but if I have the fan going only, there is no noise. As soon as I turn off the AC, the noise starts. What could be the cause and how do I fix it? What do I need to fix and what are the steps to do it.

Thanks

Sounds like the A/C pump is making the noise. Possibly the clutch in it is going out. There really is nothing you can do except confirm that the noise is coming from it. It will be in the engine compartment with a pulley run by the drive belt. The reason you can't do anymore is because the pump and a/c is under pressure and the freon is not healthy for you to breathe and it would be dangerous for you to do anything. You need a mechanic to discharge the a/c and replace the pump if infact the noise is coming from the pump. Let me know how this turns out.

What could be causing loud grinding noise when i switch on aircon? Aircon now not working but only makes loud sound.


Sounds like the bearing or part of the clutch in the A/C compressor has failed, or possibly component on a/c fouling on something due to recent repairs however would be unlikely and probably just a coincidence..

Check A/C compressor turns by hand, should be firm but not make any noises.

Check for fouling components related to a/c compressor clutch.

TAPPING NOISE, NOW IT WON'T GO INTO GEAR WITHOUT LOUD GRINDING NOISE AND ACTS LIKE TRANSMISSION WON'T ENGAGE TO DRIVE


If it is an automatic transmission, first check the fluid level. If it is low, fill it up and try it again. If the level is fine, then there is a bigger issue and you should seek a professional's help.
