Try this first==> Press and hold the "Front Defrost" and "Recirc" buttons together, and release only when the lights on both buttons start to flash back and forth between them. This procedure starts a system self-diagnosis of all components, sensors, etc., and then resets all the settings to the appropriate normals. The test runs for about 15-20 seconds, then the lights stop flashing as all returns to normal.
