Troubleshooting help needed-AC pressures

If it's a TXV they can fail open but in that case the low side will be too high, there will be little to no superheat, and the high side will be too high. High side of course is affected by OD temp as well as load.

Are you certain when you took pressure readings that you had the manifold valves CLOSED?

OK, now I understand how these gauges work....I'm a complete IDIOT!
I found a cutaway drawing... All right, I need to re-evaluate my situation as I probably messed it up. So my manifold valves were open but the charge hose was parked on the manifold so I'm not sure if it mattered or not if it was open because the fill hose was not hanging open to atmosphere?
