Need help troubleshooting air conditioning

I doubt I overcharged the system because I only squeezed the trigger for a split second to get a pressure reading. Then, when I held the trigger down, the pressure either remained constant or dropped slightly. I think the pressure in the can was not high enough to overcome the pressure built up on the low side of the system.

I finally paid a mechanic $40 to diagnose and they said the compressor was bad.

HELLO, Does that sound familiar? From what I read it sounded to me like the compressor was bad. If he (mechanic) comes back and wants to replace drier or accumulator, expansion valve or orifice tube go ahead and do that which is normally done when a new compressor is replaced.
glad u found the problem,

one more thing; recommend don't buy your parts off the internet or you might end up doing a wild goose chase like I did when they sold me defective parts then had to do the whole thing all over again. uuurrgg
