Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less. Sounds like the window motor had failed. Try hitting the door while pressing the window button. See if it jars loose. Also if you run the key and hold in lock or unlock it will raise or lower the windows as a customer convenience. See if the window motor now operates while using the switch and hitting the door. If you hear nothing then it's a failed motor. Hope this information helps. Let me know if you need more info I am here to help. Lou
