1995 f350 7.3L Little red button on dash?
 

There is a little red button on the left side of my dash by the steering wheel. It seems to do nothing when I press it. Anyone know what it is supposed to do?

Where did you purchase the truck? The past owner may have had something in there that was removed at time of sale.

Sounds like a valet switch for an alarm.
