Reasons for the Left Front Window of Teana Not Being Able to Roll Up or Down
2 Answers
Glass does not roll up or down when it reaches the bottom or top in time. Many vehicle electric window switches do not work or the window glass cannot roll up or down in place, which is also related to daily operation errors. When using the electric window regulator to roll up or down the glass, when the glass reaches the bottom or top, you must release your hand in time, otherwise it will compete with the mechanical parts of the vehicle, and the motor will naturally self-destruct. Here is some related knowledge about the Teana car: The Teana is a flagship mid-to-high-end luxury sedan under NISSAN. With new technology, Teana perfectly combines Driving Technology and Comfort Technology, bringing the design concept of mid-size sedans to a new level.
I've been repairing cars like the Teana for over ten years, and the most common issue with the left front window not rolling up is a burnt-out or worn motor, especially since the left front window is used more frequently and is more prone to problems. Another common cause is poor contact in the door switch button; sometimes dust or water inside the switch can cause it to malfunction. Additionally, a blown fuse can also result in no power, which can be checked in the fuse box—usually it's the 30-amp one that's broken. Wiring issues are also not uncommon, such as short circuits or breaks due to aging wiring harnesses, especially after rain or car washes when problems are more likely to surface. It's also possible for debris to get stuck in the window track, particularly when parked under trees where leaves can fall in. I recommend first trying the main driver control switch; if the other windows work fine and only the left front doesn't, then the motor is likely the issue. If none of the windows move, then you'll need to check the fuse and the central control system. Safety first—don't force the button if it's stuck; take it to a professional shop for inspection. Otherwise, not being able to open the window on the highway can be dangerous.
