When the cruise control on your 2002 Jeep Grand Cherokee suddenly stops working, there are several potential causes to consider. Here are some troubleshooting steps you can take to diagnose and potentially resolve the issue:

Check the Cruise Control Fuse: Start by checking the fuse for the cruise control system. Look for the location of the cruise control fuse in the vehicle's owner's manual or fuse box diagram. If the fuse is blown, replace it with a new one of the same amperage rating.

Inspect the Cruise Control Brake Switch: The cruise control system is designed to disengage when you press the brake pedal. A faulty brake switch can prevent the cruise control from engaging. Check to see if the brake lights are working when you press the brake pedal. If the brake lights do not come on, the brake switch may need replacement.

Examine the Cruise Control Buttons: Check the cruise control buttons on the steering wheel for any signs of damage, wear, or sticking. If the buttons are not functioning correctly, it could prevent the cruise control from engaging.

Verify Vehicle Speed Sensor (VSS) Operation: The cruise control system relies on the vehicle speed sensor to determine the vehicle's speed. If the VSS is malfunctioning, the cruise control may not work properly. Other symptoms of a faulty VSS could include issues with the speedometer or transmission shifting irregularities.

Check the Cruise Control Module: The cruise control module is responsible for controlling the system's operation. If the module is faulty, it may not send the proper signals to engage the cruise control. A professional diagnostic scan tool may be needed to check for any stored trouble codes related to the cruise control system.

Inspect the Throttle Cable and Linkage: The cruise control system uses the throttle cable and linkage to adjust the throttle position and maintain a constant speed. Any issues with these components could affect the cruise control's ability to function correctly.

MY 1996 Cherokee has the same problem. When I push the cruise button on the steering wheel cruise light comes on but wont engage. If I push the button by accident on long trips after letting go of the gas pedal I can feel like it wants to engage. Super scary cuz its almost like it dont want to stop
