Hey guys,
I replaced the solenoid but it didn't make much difference
What is my next option? What you all think?

This the correct pressure for 134A.
100°F (38°C) 50-55 psi / 345-379 kPa 315-325 psi / 2172-2241 kPa

I thought with the high side pressure being too low you might have an overcharged system. Could also be the compressor itself being it's used?

Maybe a stuck thermal expansion valve ? Who knows.. Meanwhile, this is what I do. Depending how you adjust it, it should blow colder air but at some point the venting may diminish - just turn it off 2 min then restart, or adjust the sensor to receive colder air
