Typical failures are either due to a front end accident or failure to keep the protective rubber boots installed..  The rubber boot that protects the manual adjust knob accessible from underneath the front bumper.  These rubber boots are easily lost when bumping the front end in a minor collision.  The rubber boot not only protects the adjust knob, but also the delicate motor mechanism.  If the rubber boots are left off, the motor tends to seize from water and moisture entering from underneath the vehicle.
