There will be a sight glass somewhere under your hood, follow the AC hoses from the condenser to the firewall and you will find it. On a warm day turn your AC on high and wait till it starts blowing cold air, open your windows, make sure the compressor clutch is engaged, the shine a light into the sight glass and look for bubbles, if you see a lot of bubbles it needs to be charged, if clear or only a bubble now and then, means something else is wrong.
