I would check fans operation. When AC on - fans should turn on.

As well as the idle should increase with the AC on. The FSM has a section on how to check the two solenoids that control idle. I was looking at it this morning, I think it was on page F-81 IIRC. I'm at the office now so don't have it with me.
