1. Check the cruise control switch. If the switch is in the “OFF” position, turn it to the “ON” position. If the switch is in the “ON” position, turn it off and then back on again.
2. Check the cruise control module. The cruise control module is located under the dash on the driver’s side. Make sure that the module is properly connected and that there are no loose wires.
3. Check the brake pedal switch. The brake pedal switch is located on the driver’s side of the vehicle behind the dash near the pedals. Make sure that the switch is actuated when the brake pedal is depressed.
4. Check the throttle cable. The throttle cable connects the cruise control module to the throttle body. Make sure that the cable is properly connected and that there is no binding or loose wires.
5. Test the cruise control. With the cruise control switch in the “ON” position, press the “SET” button to set the desired speed. The cruise control should engage and maintain the set speed. If the cruise control does not engage, repeat steps 1-4 and try again.
If you have gone through all of these checks and the cruise control still is not working, you may need to take your vehicle to a qualified mechanic.
