Hello all,
my wife has an 08 yaris with a/c problems and before i replace the compressor i want to make sure its the problem.
A/C blows hot air
Compressor kicks on the clutch is working
the low side has hi psi 70ish or around that while running.
any help would be greatly appreciated.

70 psi is a bit high on the low side, but probably OK. Do you have a gauge set to measure the high side as well? If not, what do you see in the sight glass on the high pressure line with the AC running, and then right when you shut the AC off?
