RE: help on recharging ac 430 ml
You just can't connect R134a to low pressure port (there is also high pressure port) and empty the can. You have to know what's the current pressure on low and high, and what are the right pressures.
First thing is to make sure you do have low in refrig. You need to check low pressure switch, compressor clutch, where are the leaks, etc.
There is more to it than just stick a can. If you invert the can during the charging process refrig fluid (vs. gas) can get into the compressor and you could damage it, do you or don't you add compressor oil, etc.
