Yep. Ford F-150s of the 90s use the idiotic electric window motors with plastic gears moving a metal rack. They always fails because the plastic strips out against the metal gears on the rack.
What's even more annoying is that they are riveted in place and have to be drilled out to be replaced. They're also installed between the inner and outer doorskins with no access. Of course Ford, knowing that they're going to fail was kind enough to stamp dimples in the door skin in front of each rivet so you can drill through them in order to drill out the rivets.
Replacement motors come with nuts and bolts.
First of all, why didn't Ford just stamp out holes in front of the rivets instead of stamping out dimples? And then why didn't they bolt the parts in place instead of riveting them? Who are these so-called engineers who have been designing cars for the last 100 years? They sure do some idiotic stuff.
