The Mode Selection Button located on the Turn Signal Lever does not change the Dash Display. Currently the Outside Tempurature is displayed and can be changed from C to F. However pressing the Button in Key positions one or two does not change the display. What could possibly be the root cause of the non working switch.

FYI: In key position 0 and pressing the left instrument button Time is displayed.

There was a model change in 1999 and I will require the last seven characters of the vehicle identification number to be sure I know what the issue might be, please repost with the requested data.

Thank you for the response. The E-46 body style uses several CAN-BUS systems to convey information, the instrument cluster utilizes what is called a K-Bus and this seems like a low voltage condition on the K-Bus. This I have also seen as an internal fault in the instrument cluster.
