I had it to air cond shop already and they could not find out. The low and high pressure is ok. The problem is not on the freon circuit, as it works ok initially, problem is after couple of hours driving (on the max position) the air does not blow as much as at the beginning (sometimes almost nothing, and I can hear the fan blowing inside the dash), and the evaporator are NOT freezing up, what made me suspect of some thing are being clogged up, until I opened it last Saturday and found nothing out of ordinary.After 18 posts.. I'm thinking it's time for you to take it to an Auto A/C shop and have the whole A/C system checked out by a Professional.
I (for one) don't understand what purging the air, from the oil & fuel.. would have to do with the A/C ??
Sounds more & more like a LOW Freon charge now.

I don't think you'd necessarily have to change the blower motor.. you said it never quits running, right?
I'd pull it and look around in there with a mirror and a flashlight, though..
