You need to reset the console:
Start the car.
Turn blowers on FULL, and open all A/C ports (Rear, front...). If you can tell, it is better to have the A/C compressor off. (Often you can't tell, or you wouldn't be concerned with the flashing lights, right?) Turn front air to PANEL.
Press simultaneously the Rear Wiper (not the intermittent) button and the wash button. Hold for 5 seconds until all lights are constant. Release buttons and allow the tests to run (two minutes or so.)
When the Rear Wiper and the Intermittent Rear Wiper indicators are flashing alternately, it is going through the Calibration Test. When the A/C (snowflake) and the Recirculation indicators are flashing alternately, it is going through the Cool Down Test. (In my case, both sets flashed alternately during the entire test.)
Tests are successful when only the Rear Wiper indicator is flashing slowly. Push it to exit the program, and you're done.
Often, after doing these tests for the first time, the Cool Down Test fails, and the A/C and the Recirculation indicators flash simultaneously (though, just these two instead of the four.) Simply run the Cool Down Test independently by pressing simultaneously the A/C and the Wash Buttons. Hold for 5 seconds, and allow the test to run.
This may take more than a few runs to finally set. Mine worked when I ran the test as soon as I started the car the next time (after the car had cooled off completely overnight). When all lights go out except for the Rear Wiper, push the Rear Wiper to exit. Success!
Some have suggested turning the compessor off and running the car for 15 minutes previous to the Cool Down Test. This did not work for me. But it is true that if the compressor is cold (with condensation), the Cool down test will usually fail. Try, try again. If your A/C compressor is in good condition, it will eventually set. If nothing seems to work, your A/C might be have a problem.
WHY don't the manuals come with this information??
