Title
Repairing Mercedes W123 Rear Power Window Regulator
Introduction
The power window regulators on W123 cars are prone to bending due to the soft metal they were made with. When they bend they can cause any number of symptoms; noisy and clunky movement of the windows, slow moving windows, or the windows may not function at all. This bending is caused by decades of use, and happens more quickly in cases where the regulator has been neglected and never re-greased in its lifetime. If the regulator is pulled from the car before too much damage is done it can often by repaired by bending the regulator back as close as possible to its original shape. If left to malfunction for too long, and if used often in a malfunctioning state, the teeth on the gears of the regulator can wear prematurely or even break off entirely at which time the regulator will need to be replaced. Additionally, in such an over-stressed condition, the regulator motor can burn out and require replacement. Avoid such situations by repairing your regulator sooner rather than later; this guide can help.
