How to diagnose A/C problem - 1999 E 430

My A/C stopped working and the EC light is on. When I had this problem previously my local dealer charged the system. This time I thought I would try to charge the system and bought a kit. However, when I connected the can of 134a, the gauge which comes with the kit indicated that my system was already fully charged. Are there some obvious things I can check before taking it to the dealer again? Thanks......Highwater
