Ok so i have an ac issue the compressor took a dive so i replaced the comp and dryer now a month later no cold compressor spins when on so i would imagine its not too low in coolant but i,m wondering about the charge amount with the parksmart sytem if 3 lbs is the correct charge or an over charge.....orob a moot point as its at the dealership to get checked out just wish they,d get to it a little quicker as its bugging me
