Cruise control does not work - 1995 Dodge Ram

cruise controls are dependent on the following sensors all working together
brake sensor
clutch sensor
auto--vehicle speed sensor
rpm's sensor
fuse for the cruise control
cruise control switch either or all not working will stop the cruise control from engaging
road speed at which you can engage the cruise control has to be above a reset speed before it will cut in and work

check cruise control fuse and check the brake lights see if brake light working because the brake light switch will deactivate cruise control when brakes is applied.if brake lights dont work either fuse blowed or switch bad.if all is good have vechicle code scan because cruise control control by PCM and vechicle speed sensor and thottle actuator control motor.

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.

Cruise controls can cease to engage if the clutch or brake light cruise switch are out of adjustment. If this happens, try placing you foot under the clutch pedal (if equipped) and lift up on it (toward you) and hold it while engaging the cruise. If it now works, it will likely cut out when you remove your foot from under the pedal. Check the brake pedal in an identical fashion. Adjusting the switch at the pedals can often solve he problem. Some vehicles (Honda, Acura, Ford, to name a few) have a plastic insert that mounts in the pedal arm which presses against the switch. These can become brittle and fracture into pieces. My Acura has little pieces of blue plastic on the floorboard around the brake pedal one afternoon and I noticed the cruise didn't work. It was the pieces of the insert that had come to pieces preventing the cruise from coming on. I replaced the insert and no more problem with the cruise.
