Was able to reset. I do not know in which year they switched from a service light to driver information display. The '99 I had had the service light. In the '03, there is a message display panel in the lower left corner of the dash. It displays messages like "passenger door open", "tailgate open", etc. About 20-30 miles before the 7500 mark, I was getting a "perform routine maintenance" message every time I started the car. You can clear the message using the button on the end of the left stalk. I was getting tired of that, however. I tried to clear it completely using the old method, did not seem to work until I noticed that the little hazzard warning light, right in the middle of the dash, under the middle of the spedo./ tach displays would flash yellow on using the key position I, hold trip reset, key position II, when the small hazzard warning indicator starts flashing yellow, release trip reset. Voila!
