All electric motors are designed to work within designated specifications.
When they operate outside these specs, it creates undue load which can lead to premature failure.
One way to reduce this load is to ensure that the bailey channels for the window glass are well lubricated.
I recommend silicon spray which is readily available from any decent hardware store or autoshop, it also comes with a handy straw for application. Graphite powder may also be used but leaves residue that may stain clothes. It is NOT recommended to use anything that may gum up over time such as grease or oil.
If you have the inner door trim off, spray the bailey channels inside the door while they're accessible.
Try to do this at least twice a year.
