Grinding, rattling, or clicking when engaging your windows is a sign of probable regulator failure. The symptoms are usually the result of the cable rusting from humidity or a failed regulator motor.


ECS now supplies OEM and aftermarket replacement regulators to restore your E39's window operation to factory, giving your super-sedan a nice added measure of practicality and functionality.


Please specify front or rear, left or right when purchasing - the product is door-specific.
