Most a/c systems require a certain amount of freon to be in the system before the compressor will be allowed to engage. If your system has leaked down below that point, you might need to add freon. Hook up a gauge to the low pressure side to see if the pressure is low and add freon if necessary.

The last ignition switch I worked on was on a 1996 Pontiac sun fire. It was located on the left side of the steering column across from the key tumbler under the plastic. I found the start wires and jumpered them making the starter turn. Next I removed the switch from the column, and with a screwdriver, I turned it until the starter once again turned. I found the tumbler assembly wasn't turning far enough to start it. There was a small metal cover on the tumbler that had popped up and kept it from going farther. Hope this helps. There are some useful videos on YouTube that may help also.

You will need a scanner to tell you what is the issue. You can purchase an inexpensive on Amazon. It is usually an oxygen sensor but you will need a scanner to show which one.
