Mine only does that when I unplug the stereo fuse so that I can start the car after the battery goes dead from leaving the fan jumper on by accident so that it doesn't overheat because the fans are set to come on at 225 or some such crap at which point it's way too hot, and I don't have a tuner, so I rigged a manual switch for the fans. Anyway 4 more days and we'll find out if it's a leap year glitch.
