hello Everyone, I had tried to retrieve codes from my '99, key on.....push, off and pass.up same time....nothing except passenger heat scale going up. Each button works, but together produces nothing. User error? I used the sticky from '05 and related addresses.Two buttons, ya figure i could get it right! thanks Ed

Hold them down for a few seconds...

I used the driver info button along with the on and off button that is next to the driver info and reset button on my 99 seville

The Eldo and Seville were very different cars after '97.

Like Vincent said, simultaneously press and hold.

And without a factory service manual the codes will only give you numbers. I assume you are a better than average mechanic? Have tools? and why are you seeking codes, What problems are you having if any? And you did read the STICKY about codes and their definitions at the top of the thread section.
