high low side pressure would indicate the orifice tube is not installed, or the compressor took a dump.

what was high side at?

Was gonna ask, what's the high side say.

Need to know high and low side pressures to determine the issue.

For me it was just a good old fashion leak somewhere each time.
Had to dye test it and replace seal(s) that leaked...

Eventually will just quit working all together.

Once was seal on the AC compressor.

Other time it was seal for connector to the dryer.
