Hope this is not too late.
You will have to clear the AC codes before the compressor will turn on.
Turn ignition on hold down the "off" and "warmer" (red button) buttons on AC panel for a few seconds. The IPC will freak out for a couple seconds (it is a segment check for the IPC).
After codes are displayed on the IPC message center, you will see the message "PCM?". Press the up arrow (on the fan speed button) until you see ACM? Then press the down arrow.
It should now display "ACM Codes?" press the up arrow. After it displays the ACM codes, it will display "Clear ACM Codes? Press the up arrow and it will then change to "ACM codes cleared".
Now, press the Ooff button a few times to exit diagnostics.
Now your A/C compressor will turn on, as long as there is Freon in the system.
