you will need a set of guages to do this, you will need to have the vehicle on max a/c with the windows closed. some visual indicators are oil around the joints on the air conditioning compressor mounted on the engine, or around the hoses and their seals. available from auto stores, and places such as target, Walmart etc... are cans with pre-mounted gauges that give recommended operating range, typically 30-45 psi on the low side (the lager hose that is cold to the touch) DO NOT CONNECT TO THE HIGH SIDE CONNECTIONS TO INJECT COOLANT OR OIL! the high side (small hose) should be warm or significantly hot to the touch, and the low side (larger hose) should be cool to the touch. while the low side and expansion chamber shoudl be cold they shoudl not be building ice, if so your pressures are incorrect. if you have a manifold gauge set you can monitor the pressures on both sides of the compressor, and with recomendations from your local a/c parts distributor they can advise you on propper operating pressures for your specific vehicle.
