What do you mean zero chance? I’ve done this before with 134a. Same process you’re doing. This is a 1234yf system. The problem I’m having is it won’t suck into the low side port. As soon as I crack the low side on the gauge it will fill into the eye glass on the manifold gauges but will not suck into the low side port.

No I’m not. Used manifold gauges and a vacuum pump. After I unhooked the vacuum I let it sit for 45 minutes. It held vacuum the entire time. After I tapped the A/C can I could see Freon go through the sight glass. It just wouldn’t flow into the low pressure line

Hi, I recently replaced my A/C condenser. It had a leak last August so I didn’t bother to replace it until now. I hooked up a set of manifold gauges and vacuumed out the system. It holds a vacuum just fine but the truck will not take Freon. Any ideas what the issue would be?
