Oriface tube plugged up?
Air conditioner charged properly, compressor running, still blows hot air

You can get the gauge set from Autozone as a loan-a-tool. That would really help with diagnosis.
Would pull a suction on the low side.his isn't pumping.
Maybe the blend door is stuck...probably not...but maybe
The OP reports the suction line is not cold, ruling that out. With a stuck blend door the evaporator (and suction line) gets cold but the air to the vents is hot because it has been redirected through the heater.
Low side too high, high side too low, both about 70 psi.
If the pressures are the same high and low side, the compressor is not doing anything. Don't need to look any further.
That would result in too high of a pressure on the high side, and too low of pressure on the low side.
That's what I was thinking, but the compressor is engaged, drag on the engine, fans come on, etc.
Cooling fans on and a higher idle does not guarantee compressor activity.
Could it be the expansion valve since high side and low side pressures are the same?
No. My guess is something was missed during your repair since the system was operating correctly prior. It's time for a thorough diagnosis/inspection.
Sounds like compressor isn't compressing... I would be trying to learn more about that compressor control valve
That's what I'm thinking. I'm having it looked at tomorrow. I'm hoping it's something simple like a post-rebuilt error. It worked great all last summer.
Well, apparently it isn't or the high side would be going up and the low side would be dropping. Idle increasing is probably just a normal reaction by the ECU to bump idle when a call for A/C has been made.
agree 100% and since the car was totally taken apart all winter including a/c could be any number of things.. none of which is easy to tell over the internet.
Might be time to take it to a pro.
Does the AC button to engage the compressor have an LED on it? If so, is it blinking or on steady when engaged?
I had a corroded ground wire to the clutch coil once and clutch would not engage
