The window in my Buick is not working correctly.
Thank you for your inquiry. If the window will not go up or down easily, or seems to shift during operation, the window regulator may have a mechanical failure. This includes a broken mechanical connection to the glass or even the window sliding off track. If the glass seems secure and will not move at all, a technician can check the electrical circuit for blown fuses or failed components. Have a mechanic, like the ones at YourMechanic, take a look behind the interior door skin and test the window’s electrical system.
