Maybe. Maybe not.

Is the EC light on?

What are the HVAC diagnostic readings (REST feature of the AC controller)? If you're not sure what I'm talking about, go to the Signal to Noise website, select AC Diagnostics Pt1 on the left, and follow the instructions. Post the first 8 readings from your car.
