How do you fix a passenger window that won't go up on a 1998 Jeep Cherokee?

To fix a passenger window that won't go up on a 1998 Jeep Cherokee, first check the fuse related to the power Windows and replace it if necessary. If the fuse is fine, inspect the window switch for faults or debris, and consider testing the switch with a multimeter. If the switch works, the issue might be with the window motor or wiring; you may need to remove the door panel to access and troubleshoot these components. If you're not comfortable with DIY repairs, consulting a professional mechanic is recommended.
