My 1999 lumina sedan 3.1 v/6 auto hot air from vents. Charged the system and the pressures are equal on both sides my gauges read 140 on the high and low side. Could this be the orifice tube? If so where the heck is it. Once the system was charged the compressor kicked in and made no strange noises. Need some guidance as to what to replace next.
