I had a problem like that once. The light would not go out either. found out that the light inside the instrument cluster that lights up the "trac off" was just burnt out. I replaced it and the problem was fixed.

If the switch stays illuminated my guess would be that the dash light isnt burnt out, if it were the light on the switch should go out still.

my light did stay on until I replaced the light bulb in the dash. its not that hard to pull out the cluster and take it a part to see if thats really the prob. I'm sure tech into has a right up on it.
