Clicking while in park

You said no A/C

Do you know where/ can you see the A/C compressor on the engine while it is running?

WATCH OUT FOR THEM PESKY MOVING PARTS - THEY WILL GET YOU IF YOU AREN'T CAREFUL!

Can you see what is going on on the front of it when that awful noise is happening and not happening?

You turn

See if the racket occurs when something might be happening on the front of of the compressor (like w/ the clutch).

You'll understand if you see/ hear the clutch making the racket!

Alrighty then

Compressor has a clutch

It's what 'engages' the compressor (the shaft/ rather pumping part of the a/c system)when you turn it on, sometimes the clutch gets messed up, sometimes it won't engage, sometimes it will drag/ grind along.

Here's the kicker, the part I wanted you to look for, If the COMPRESSOR is "locked up" (shot, can no longer turn). It may sit there minding it's own little torn up business,

Then the clutch and its pulley which are turning sorta happy go lucky while the engine runs, suddenly, from being turned on "ENGAGES" the compressor.

Well Mr. Compressor is broke and cannot/ will not turn at all

Clutch is now hooked to it.

Clutch/ Clutch pulley wants to turn but now the compressor is dragging it down, lots of times we get a terrible racket, burning belt, engine may wanna start stalling down.

See-uns how you said this racket is an off/on kinda noise, the a/c also cuts off and on when it's running, This is the sole reason I'm having you look at this as a possibility.

This may not be your problem, but this is a quick EZ way to eliminate the A/C compressor and clutch out of the equation. If this only happens when the clutch engages, The car may run just fine if you simply unplug the connector on the clutch on the compressor until you can replace the compressor.

This is a "typical" a/c clutch in operation (yours may look a little different)

Notice the center part does not spin until it is called upon (turned on by you or normal operation turns it on and off)

When the center clicks in (engages) the compressor's internal shaft (pump) is now turning,

that is, unless the compressor is locked down.

The video I found shows a compressor working normally.
