baught a 99 3500 24v 95000 miles
cruse lites up on dash but dosent function
any ideas?

 

The cruise servo is under the driver side battery tray...check the vacume line on the servo - often the battery drop acid on the rubber line and eats through. Replace the line or a section of it and that should cure the problem..

 

THANKS DOC. I"ll try eyeing it first thing in the morning.
You guys are great.
