Causes of 1999 Jeep Grand Cherokee Cruise Control Not Working
Before diving into the solution, it’s important to understand some of the common reasons why your 1999 Jeep Grand Cherokee cruise control may not be working:
Faulty Cruise Control Switch
The cruise control switch is responsible for turning the system on or off. When the switch is faulty, the system may not work as intended. This could be due to damage, wear and tear or a loose connection.
Malfunctioning Cruise Control Module
The cruise control module houses the electronics that control the cruise control system. When it malfunctions, it can lead to a variety of problems, including the system not working as intended.
Brake Light Switch Failure
The cruise control system is designed to disengage when the brake pedal is pressed. The brake light switch is responsible for detecting when the brake is applied and sending a signal to the system. When it fails, the system may not work correctly.
Speed Sensor Issues
The speed sensor is responsible for detecting the vehicle’s speed and sending a signal to the cruise control module. When it malfunctions, the system may not be able to maintain the desired speed, leading to the system not working as intended.
Steps to Fix 1999 Jeep Grand Cherokee Cruise Control Not Working
Now that we’ve discussed the common causes of cruise control system failure in the 1999 Jeep Grand Cherokee, let’s take a look at the steps you can take to fix it:
Check the Cruise Control Fuse
The first thing you should check is the cruise control fuse. A blown fuse could be the reason why the system is not working. To check the fuse, locate the fuse box and look for the cruise control fuse. Use a fuse tester to determine if it’s blown or not. If it is, replace it with a new one of the same amperage rating.
Check the Cruise Control Switch
If the fuse is not the issue, the next step is to check the cruise control switch. To do this, remove the switch and inspect it for any signs of damage or wear and tear. If it appears to be in good condition, check the electrical connections to ensure they are secure. Reinstall the switch and test the system to see if it’s working.
Check the Cruise Control Module
If the switch is not the issue, the next step is to check the module. Disconnect the module and inspect it for any signs of damage or wear and tear. If it appears to be in good condition, check the electrical connections to ensure they are secure. Reinstall the module and test the system to see if it’s working.
Check the Brake Light Switch
If the module is not the issue, the next step is to check the brake light switch. To do this, locate the switch near the brake pedal and check for any damage or wear and tear. If it appears to be in good condition, check the electrical connections to ensure they are secure. Reinstall the switch and test the system to see if it’s working.
Check the Speed Sensor
If none of the above steps have resolved the issue, the next step is to check the speed sensor. To do this, locate the sensor and visually inspect it for any damage or wear and tear. If it appears to be in good condition, check the electrical connections to ensure they are secure. Reinstall the sensor and test the system to see if it’s working.
