Hello,

When an A/C does not blow cold air, it can be due to few different reasons.
It could be simple as Freon being low and due to the low pressure in the A/C system the compressor is not coming on.
If the Freon is low then you will have to add Freon. However you will have to make sure it is not just simply leaking out.

Here are couple of helpful videos:

It can also be a bad relay for the compressor. The compressor relay is located under the hood just in front of the radiator (see diagram). Check the relay for corrosion or burn pins.
You can also test the relay:

You could also have a bad A/C compressor.

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
