I don't know if it's the A/C relay switch or the A/C compressor. Please let me know.

HI, welcome to 2CarPros.

May I ask if the compressor is kicking on?

Here is a guide on how the system works so you can better understand it:

Okay, if the compressor is kicking on then it is probably low on charge.

You can go to any parts store and buy a can with a gauge on it and add gas yourself.
Make sure you read the can and the gauge so you don't over charge it.

If you put a can on it and the gauge says its full IE in the green range then we have another issue.

Here is a guide on how to add gas:

Let me know how it turns out.
