What would make the cruise control not work on a 1997 Dodge 2500 Van?
There are magnents on the half shaft(front wheel drive) or the drive shaft( rear wheel drive)and a magnetic sensor positioned close to these magnents. If one or the other is damaged or missing the cc wont work. On my 2000 Dodge Ram Van, there's a vacuum line behind the passenger side headlight. If this is disconnected, the cruise control will not work. I found out from the clerk at the dealers parts dept. It's worth investigating.
