mY a/c COMPRESSOR IS AUTOMATICALLY OFF (i GUESS TO SAVE THE cOMPRESSOR)
iF i START IT, i GET THE ERROR "vERY lOW rEFRIDGERANT" AND IT WON'T START
THE ac so I can't er-start the A/C to recharge the system...
When you hookup the line to the low pressure recharge port is usually enough pressure in the recharge bottle to override the low pressure switch unless the system is totally dry, if that is the case then take to a shop to find out why, you may have a bigger problem then just a low charge.
closed system running out of stuff would point me towards a leak
Sounds like faulty pressure switch.
