Unless you spent $1200 from Chrysler for DRB software for your scanner doubt if it's reading right.
The common OBD system doesn't start until '97.
Most common causes of no cruise are a rotted vacuum hose under the battery or a bad brake light switch. Since the switch is only $11 from Napa I find it easier to just swap in a new switch rather than test the old one.

I checked the brake light switch today and it is working right. and i have the little green light on the switch on the steering wheel coming on. so what should i check next?.

The switch is working. what i think is the problem is the computer. P1683 says S/C power relay circuit. the computer controls the speed control. i checked
the servo wires and they are good. all vacuum lines are fine. i am not 100% sure about the computer being bad. would like to fix it myself before going to ***********.
