I was just driving on a cool early morning ND I started feeling AC breeze ND that was how it started I turned it off after sometime it came on back

Now I notice the compressor picks up Everytime I start the Car

Seems you have a short circuit somewhere in the wiring.

The compressor clutch is normally turned ON by ground controlled relay from the PCM which get triggered from the Hvac switch via a bus signal .
To get reasonable answer ,u need to revert by answering this question.
What is the repair history of the AC ?
Any recent electrical repair done on the car recently just before this issue?
On what condition does the compressor turn itself on ?

Your compressor clutch is designed to be turned on by the ground controlled compressor relay by the PCM which gets signal from HVac switch via the bus system.
To get seasonable response to this issue ,you need to revert by answering this question :
1.What is the repair history of the AC?
2. Any recent electrical work done before this issue?
2.On what condition does the AC turn itself on?

This is what I'm still trying to get

Just use your eyes and trace the AC wires. There should be some abnormality down the way. If you cannot do this get an electrician and direct them to do it in front of you.

Okay I'll try that today at a rewires workshop

The AC compressor is designed to be turned on by the AC compressor relay via the PCM.
PCM gets the turn on signal via a bus communication signal from the HVAC switch on your AC panel that your switch on.
For a contantly ON compressor that means short to power or ground has occurred along the signal route.
To troubleshoot this and identify the culprit ,you need to start to unplug or removing all the element mentioned along the route aone by one till the AC compressor goes off .
