And I have to ask....why?
Because it's there? LOL
Initially I thought it not working might have something to do with my intermittent draw, but it doesn't seem to be related. And I thought that's the way the OE clusters work, having the ability to view the mileage by pressing the cluster button any time. My cluster was a Dorman reman, then I sent it in to have updated with the tranny gauge and LEDs, so no real history on it and if it ever worked that way.
