I am not convinced there is a problem here. Under the right conditions, air conditioners sometimes have a bit of visible condensate in the output air. It's not a big deal. I've seen it happen many times in many different vehicles under mildly warm, humid conditions. Sounds like Houston this time of year, eh?

To test if the evaporator is icing up, let the a/c continue running. The ice blocks airflow; eventually you'll notice less and less air coming out the vents despite more and more fan noise. This car does have a temp sensor for the evaporator, it's supposed to shut off the compressor when the air coming off the evap falls below ~38 degrees. The temp sensor is buried in the HVAC box, the electrical connection for it plugs in kind of near the throttle pedal.

Try flipping it into 100% recirc mode when it begins misting. I bet that stops it right away. The coming warmer weather will also take care of the problem...
