Don't start new threads about the same problem, don't call R-134a "freon", and don't "bypass your compressor".

OK. We don't recommend adding refrigerant without using a set of gauges for both low and high side pressures. That technique can usually get one close.

However the best way is to evacuate and fill by weight (e.g. at a shop). But since it is likely your refrigerant has leaked out, the leak needs to be fixed or the added refrigerant will leak out as well.

Compressor comes on when the refrigerant is need to bypass anything.

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
