where is low side port on a/c on 1989 corvette
Right on the dryer itself, might still have a black or even semi clear cap on it. Note this system is an R12 unit unless it has been upgraded to 134A. The charging ports will still be in the same position just changed over to fit the 134A charging units. Do not mix R12 with 134A. So do you know if it is old R12 or been converted?
