AC charging
before the moderators get mad 
i tried to do a search in the forum and couldnt find a clear answer
how can i charge the AC system with freeon after an AC flush, the system right now dosent have any freeon in it so the compressor stays off and it wont take new freeon
i found a couple of post about the AC system reset and diagnostic (holding reset button) but it didnt really explain how to charge the AC when the compressor is empty.
thanks in advance

I think this is something you should hand over to the dealer.

nvm after a little more research i was able to do it 
i had to press the reset and charcole filter button together for about 8 seconds, then press and hold both auto buttons to reset the system, once i did that the EC button turned off and the compressor started working which allowed me to recharge the system and now its working good
