Hello 1st thing to check is that the AC rad / condenser is clear of any debris and there's nothing in front of the air flow to it, next ensure that the AC pump drive belt isn't slipping and if any doubt replace it.
high pressure pipe from pump is hot going to condenser then rad ? pump is hot but high pressure pipe at the top by filling valve ic cold
Hellothat sounds right so its likely that the compressor is working fine If the car's temperature control is OK ( does it do hot as well as cold?) then its possible the AC rad inside the car is blocked up.
