'01 Suburban Odometer Problem

[trailrunner]

the odometer/trip odometer display has stopped working on my '01 'burban. it's stuck in "trip odometer" mode and won't switch back.

any one ever had this happen before?

and since i'm writing ...... what's the trick for reseting the "change oil" light. i remember that it involves the ignition switched on, truck not running and depressing the gas pedal some number of times. what's the details that i missed?

thanks
