Those pressures are WAY too low as I said in your other post. Did you pull a vacuum? Did you clear the codes to enable the compressor before recharging the system?

You should have been close. You don't get all of the 2nd and 3rd cans but it is real close.

If it was mine I'd add a 4th can and see what happens. Starting at that low pressure it should not hurt anything.

Watch the pressure as you add the next can.

you added way to much freon....if you dont let the excess out you will blow your compressor....cars nowadays can only take a can and a half maybe two tops.
