1. Faulty Window Regulator: The window regulator is a mechanical or electrical mechanism that controls the up and down movement of the window glass. If the window regulator on the passenger side or rear is faulty, it can prevent the window from moving properly.
2. Damaged Wiring: There may be a problem with the electrical wiring that connects the window switches to the window regulators. Check for any broken or loose wires that could be interrupting the power supply to the passenger and rear windows.
3. Faulty Window Switch: The window switches are responsible for sending the electrical signal to the window regulators. If the passenger side or rear window switches are faulty, they might not be able to activate the window regulators, causing the windows to not work.
4. Blown Fuse: Some vehicles have fuses that specifically control the power supply to the power windows. Check if there is a blown fuse that is related to the passenger side or rear windows, as this can also cause them to stop functioning.
5. Door Lock Switch: In some cases, the door lock switch can also affect the operation of the windows. Ensure that the door lock switch is functioning properly and is not preventing the windows from being operated.
To diagnose the exact problem and resolve it, it is recommended to take your vehicle to a qualified mechanic or auto electrician who can inspect the window regulators, wiring, switches, and other related components to determine the root cause of the issue and perform the necessary repairs or replacements.
