yeah mine has no vacuum ever. My high side goes up to 450 and cuts itself out. I changed the orifice tube and vacuumed and recharged and it does the same thing. Where should the air blow out at on max ac mine blows out the defrost on max. The ac doesnt really work untill the fan clutch kicks in untill then it just gets kicked out by the high pressure switch. The heater control valve prolly doesnt have anything to do with it but it doensnt have any vacuum and i was wondering why. My condenser is a bit bent up from bugs but it does have some air flow, so it should be working with the fan clutch off right.
