    MMM, that's like waiting for the engine to fail before you change your oil. :)

    We got into the fan, cleaned it all out, and unplugged battery to reset.

    You can use an OBD2 reader and your phone with Dr. Prius app to monitor the temperature readings of the battery pack in real time. You can also use the hybrid assisstant app to speed up the fan to full speed. These are very easy tools to use. The catch is there's tons of junk OBD2 sellers online. So use this buying guide to make sure you buy one that will actually work: Hybrid battery diagnostic and repair tool for Toyota and Lexus
