2007 GM: Oil Change Reminder, driving me crazy...
 

We have a 2004 and a 2007 Grand Marquis. The '07 has an oil change reminder on it that is difficult to reset. You can follow the instructions for resetting the *&$# thing and most of the time it doesn't reset.
I can't imagine what some engineer who set this system up on this car thought this was a good idea for...
Anyone got any ideas for consistent results to clear the thing?
