when i first start my car the a/c blows very cold after a few minutes the compressor disengages and of course blows warm air.... pressures are fine could this be the high pressure switch , low pressure switch or a clogged orifice tube i dont think its the orifice tube because i believe that if it were that it wouldn't blow cold at all. ty for any assistance in advance

thank you for your posts

i ended testing system finding it was the compressor that is the problem reclaimed refrigerant today replace compressor , accumulator, low side pressure switch high side cut out switch and orfice tube will be putting system on vaccuum in the morning and recharging with refrigerant also the orifice tube was littered with metal shavings not completely clogged so still effective up until compressor failure
