No power to compressor or relay. Air conditioner light on dash has no response from switch.

Check the relay center under the hood. It will be near the battery. The cover is labelled. Use a test light to check the operation of the air conditioner relay.

Correction: Your car is one of few that actually have the air conditioner relay located on the top of the left hand main junction box. Locate the air conditioner fuse in the fuse panel and see if it is burned. See if the switch is receiving power.
