 discovered a switch w/ a light on it on the right side of the dash pod.  The
 owners manual says it is an extra switch spot.  Mine makes a click noise in
 the dash pod area and the little light comes on.  There are no foglights on
 this van nor does it look like there ever was.  It clicks when the switch is
 at the midway point.  Any one have any ideas as to what the heck it is.  It
 is an 87 wolfsburg edition if that helps! >>

sometimes the OEM fog light switch was added here.   if its not that, then
its aftermarket whatever it is.   ive seen vans w/ an aftermarket alarm here,
and even a switch in this location which was labeled "warp drive"
no kidding!!  :<)
