Cruise control is the hardest to diagnose sight unseen. First it takes knowing what car this is and inspecting connections and for any vauuum leaks if applicable. Then one would need to get wiring diagrams and hook up a scanner to see data and test components. You might have a code stored that could indicate another issue which is related to sensor input being incorrect. Unless you have pretty good diagnostic experience this should be left to a pro. All you can do is inspect and listen for anything not normal.
1. Check if the cruise light turns on when the cruise is set while the vehicle is driving. If the light illuminates, but the cruise will not operate, then check vacuum to the cruise servo and the wiring to the cruise servo.
2. If the cruise set light does not illuminate, check the brake switch and set switch inputs to the cruise control unit.
3. If those inputs are good, verify the powers and grounds and the park or neutral switch inputs and the speed sensor input. It is easier to check each terminal at the cruise control module that each switch separately.
OTH
1. Check to see if fuses 14 and 25 are blown.
2. At the cruise control actuator check for battery voltage at terminal 2 and 13 with the main switch on. Check for an input to terminal 5 when the set switch is pressed.
3. Check terminal 14 for a ground input with the shifter in the drive position.
4. Check for a speed sensor input on terminal 12 with the vehicle moving.
5. Check the cruise control actuator unit. ER POSSABILITY DEPENDING ON THE YEAR COULD BE:
It can be faulty
cruise control switch. If the switch is replaced, then it can be wiring issue
or faulty cruise control board. But as the switch is replaced, get the voltage
at the switch tested to confirm the switch is actually receiving voltage. If no
voltage received at switch power supply wire then, apply external 12
volt power to the cruise control switch wire and then see if cruise control
comes ON. If yes, then you know wiring is issue.
