SOURCE: pick up Nissan air conditioner system.
CHECK YOUR CONDENSER IT MIGHT NOT BE GROUNDED. MINE DID THE SAME THING IT WOULD COME ON AND THE CONDENSER WOULD RUN FOR A FEW MIN. THEN KICK OFF AND NOT COME BACK ON MAKING IT BLOW COOL AND NOT COLD

OK, the compressor may be squealing due to a lack of lubrication internally, causing a squeal of the belt or the compressor is in need of replacement.
May cost anywhere from a few hundred up for a new one installed.
First, Check belt tension for belt problems.
Or, the clutch is squealing on the compressor at low speeds.
More likely a belt, I think.
Try charging the system with oil and r134a in a can along with sealant.
Sometimes putting a few ounces of oil in the system will quiet the compressor down.
Good luck on this repair.
