A grinding or crunching noise and then the glass drops, a motor that hums while the glass stays put, or glass you can slide by hand, is the cable window regulator. If the motor hums, the page says you may only need the regulator. E90 regulators are often sold without the motor. F30 front regulators are often the assembly with the motor. Initialize one-touch after the install or anti-trap misbehaves.
