Timing for Replacing the Power Window Regulator
①Window Won't Move：If the window cannot raise or lower, or there's no response when operating the switch, it may indicate a faulty regulator that needs replacement.
②Unusual Noises or Sticking：If you hear abnormal noises or feel resistance while using the window regulator, it may mean internal parts are worn out, so it's advisable to check and replace it.
③Tilted Window：If the window tilts during operation, this indicates damage to the regulator's bracket or guide, necessitating replacement to ensure proper function.
④Control Switch Not Responding：If the window switch does not respond while others do, it could be an issue with the regulator, requiring inspection and potential replacement.
⑤Frequent Failures：If the power window regulator requires frequent repairs, consider replacing it to avoid further inconvenience and costs.
