1. Check the fuse: Locate the fuse box and identify the fuse for the passenger side power window. Check if the fuse has blown. If it is blown, replace it with a new fuse of the same amperage rating.
2. Test the relay: If the fuse is not the issue, the next thing to check is the relay. The relay is responsible for providing power to the window motor. You can remove the relay and check it by connecting it to a 12-volt power source. If the relay clicks, then it is functioning properly. If the relay does not click, then it needs to be replaced.
3. Check the wiring: If the fuse and relay are both in working condition, then the problem may be with the wiring. Check for any loose or damaged wires that connect the switch, relay, and window motor. Ensure the wiring harnesses and connectors are correctly connected.
4. Test the window motor: If the wiring is in good condition, then the problem may be with the window motor. Apply power to the window motor directly using a 12-volt power source. If the window motor operates, it means the motor is functioning properly and the issue lies elsewhere in the electrical system. If the motor does not operate, it needs to be replaced.
5. Switch: If the motor operates with the direct power source, it is likely that the switch is faulty. Replace the switch.
Remember that electrical issues can be complex, and it's always a good idea to consult a professional if you're not comfortable working with electrical systems.
