To troubleshoot cruise control issues on a Jeep Cherokee XJ, you should:
1. Check the owner's manual: Your owner's manual will list the fuses related to the power distribution system that *could* indirectly affect the cruise control. These are likely fuses for things like the powertrain control module (PCM) or related circuits. Look for fuses associated with the ignition system, instrument panel, or other relevant areas.
2. Inspect the cruise control switch: Make sure the switch itself isn't malfunctioning or damaged.
3. Check for any related error codes: A scan tool (OBD-II) can read diagnostic trouble codes (DTCs) that might pinpoint the problem.
4. Have a mechanic diagnose the issue: Because cruise control is an integrated system, it's often best to let a qualified mechanic diagnose the exact cause of the malfunction.
Simply searching for a "cruise control fuse" won't be productive for the XJ. The problem is likely more complex than a simple blown fuse.
