Have the driver's door window open and the front bonnet open,
we are going to listen for a clicking noise, the noise that we are listening for is the Compressor engagement being activated after three seconds from the control panel.

Start the engine and switch on the air conditioning by pressing the AC button (with a request for maximum cold temperature and the passenger compartment fan running).

If you hear that clicking noise, then it is most likely that you have a leak from the AC system or a possibly in need of a top up do to service of the system not been carried out.

Otherwise if you don't hear that clicking noise then there is a case that the Compressor clutch is not being engaged.

Do to the following reasons

1. fuse blown in the UPC in other terms the fuse box (engine compartment)

2. AC Compressor faulty

3. AC pressure switch faulty

4. If there is not the slightest bit of pressure left in the system which is very unlikely.

I hope this information was somewhat helpful for a real diagnosis test a diagnostic tool is needed.

Low freon charge. Have system charged and check for leaks.

The most common cause is a leak in the system and a low refrigerant charge. Have a set of AC gauges hooked up and see what the system pressure is on the low side.

Vibration in intake manifold on cold start up eventually goes away whenhot

Sometimes a weak idle air control (IAC) solenoid can vibrate and set up a reverberating noise in the intake ducting that sounds like a fog horn. This can usually be fixed by replacing the IAC solenoid.
