Cause of failure

From my observations, the design of this regulator assembly and motor is flawed. The center brace that

actually clamps on to the window is driven up/or down by a single cable. Were the cable connects to thebrace is where the component failure occurs. Since the motor applies continuous force during the roll up

action, the plastic housing isconstantly stressed and eventually

fails. As illustrated here, the cablehas a square metal section that fits

into a plastic slot that is connectedto the window clamp. This section

supports the weight of the windowand drives the window up and

down. Once the top section of thisslot fails, the weight of the window

is no longer supported and cannotbe rolled up. The bottom portion of

the slot may remain in tact and thatis why the window may continue to

operate with the down action.Applying epoxy to the damaged

portion may actually fix theproblem, assuming no other damage

has been done by continuousattempted operating of the already failed system. The replacement system appeared to have used some

type of resin to re-attach and re-seal the failure point.
