The A/C is not putting out cold air and would not take any more Freon. so, the plan is to vacuum and recharge, the R134 oil checker shows it needs more pag 46 oil, my question is how much?

Hi,

As far as the PAG oil, I attached the specifications below. However, if the system is fully charged, you should be getting cold air unless something different happened.

When the A/C is on, do you hear the compressor engage? Also, have you checked the blend air door actuator in the vehicle to make sure it is working?

Let me know. Here is a link you may find helpful:

Take care,
