When i turn my air conditioning on there is a loud clicking from under the hood. on 2006 Ford Explorer

When i turn it off the sound goes away. Heater & AC work great. what is that clicking noise?

sounds like the compressor clutch kicking in and out which could mean you need to check for leaks and top up freon
Thank you
no problem!
