A cruise control is an example of a closed loop servo.
Speed control is Chrysler's name for cruise control. The speed control relay on your Wrangler supplies power to the vacuum servo for the cruise control. This servo opens or closes the throttle plate in the throttle body based on commands from PCM when your cruise control is set.
Yes.
There is no isolated fuse for the cruise control. It all runs off the 20A gauges fuse. If you are having trouble with the cruise control I would check the Cruise Control Module or the Cruise control Servo. What symptom is occurring?
to the right of the brake booster
Leak in vacuum line to cruise control servo (actuator). Most commonly caused by vacuum line being inadvertently bumped & disconnected while someone is working under the hood or there may be a crack in the line. Another possibility is a bad servo. I believe the servo is located in the space between the battery and radiator (not sure on this because I have a 2001 Dodge Ram 2500 with the diesel engine which does not use a servo for the cruise control.) Once you locate your servo, follow the vacuum line from it & check for cracks. Yet another possibility is the servo cable may be disconnected from the throttle body.
You can unplug it at the servo itself. The servo is the part that has a cable coming from it attached to the throttle body. You'll see see a wire harness plugged into it.
who ever said that a dodge ram diesel does not have a servo it is not true. I have a dodge diesel 2001 and it has a servo and the answer to this question is it had a vacuum leak in the servo vacuum line, changed that and cruise control worked great. the servo is under the drivers side battery.
Reconnect everything EXACTLY as it was prior to the manifold replacement.....look for either a disconnected vacuum line or electrical connector to the cruise control servo - check the fuse that supplies power to the cruise control - check for 12v power to the servo (got a test light or a multi-meter ?) hope that helps.....
E62 is a vacuum solenoid problem with the cruise control. E92 is a heated windshield request problem. E99 is a servo apply problem with the cruise control.
The servo is under the battery. The engine computer controlls it.
