Pontiac G6 2007 AC problem.

[Gedalya]

Hi, I have a Pontiac G6 2007, My AC won’t work. I took a refrigerant can with a gauge and checked the pressure on the low side. It cam up to 150 PSI when the car was hot and 80 PSI when the car was cold. (I don’t have a regular gouge or any other AC tools at the moment). What does it mean with these readings?
I bought the car like a half year ago, The AC clutch would engage and disengage back then, but it wouldn’t work. But when I checked now, it doesn’t engage at all.

Thanks.

Hard to tell without a manifold gauge set reading high and low. It could be over charge?

80lbs on the low side is quite a bit high. Hard to determine without seeing the high side pressure also.
