Well now you are talking,

because I do not have any refridgerant in the system and planned on testing compressor and all of the above.

what I mean is that while you are driving, the sunroof will suck air out of your vents, and there's nothing you can do about it. you will feel them blowing on you.

you won't be able to turn on the compressor without the system being charged with refrigerant. If you want to test it "dry" you will have to run current to it manually.

Please clarify... because as soon as the car is started the vents blow as though I have engaged the heat/ ac.... but controls are off and not in position for car to react.

if it happens as soon as you turn the car on, then it's not related to the sunroof being open.

i had a car do this once because a vacuum line associated with the heater controls had come loose in the engine compartment - have you taken a look to see if that has occurred?
