My AC doesn’t blow cold and the compressor is not kicking on. I filled with more refrigerant and still not blowing cold.

Welcome to 2CarPros.
First, this could be a couple different issues. To determine if the compressor is working correctly, I need to know what the pressures are on both the low side (where you add Freon) and the high side of the system. To do that, you need an AC manifold gauge set. Here is a link showing one being used to vacuum and recharge a system:

Now, if the compressor isn't turning on, it could still be low on Freon, but I don't know if that is the case. Do you have a gauge which indicates when the system is charged or pressures?
If you take a look at this link, it shows a general low pressure gauge which comes with the Freon. This link also explains how to recharge the system without both gauges.

Let me know if that helps, if you have other questions or need help. Also, if you can provide the pressure readings, it would help a lot.
Take care,
Joe
