Why would you bleed refrigerant?

So you really have no idea what the charge level in the system is then?

5 pages deep, and honestly could not tell what the vent temps are at this point.

My step dad is trying to help as well that’s what he told me to do cause he said it was on the low side was high . I’m not ac Tech I’m 22 I build engines and transmissions I’m trying best to learn ac and everything that I can

Reclaim refrigerant, do a proper charge procedure and then get readings and vent temps. Stop reading the internet on charging by pressures. If that was accurate, you could just charge with magic can products and there would be no need for a/c equipment.

Ok, well then the basics.

We charge systems by weight. Once you have the correct weight in the system we evaluate the system by measuring pressures and temperatures.

You are at a point where you need to recover the refrigerant, evacuate and then charge the full charge by weight.

Ok I’ll reclaim it and would any scale work for small cans Ike Walmart ?

Will do . I’ll report back when I get everything

You don't use a scale with small cans. Just know how much is in each can. Be as close as you can to the vehicle capacity.

Ok well I just bought one so I’ll try and get the last can half way and that should put me close to 68oz and this just started to happen I think my OT came out or something the rear air is blowing 60 right now and the front isn’t even cold

Update

So I charged it to close as 68oz as possible it’s like 98 for the Ambient temperature the low was 47psi high side was 203psi and this was during the night time . It was blowing 60 degrees out of the vents at idle and I found that the front OT had a little trash in it so I put a new one in and now I have air in the front as well from what I’m reading it’s still low for both sides
