I am one of a good handful of owners who have installed the Vader window lift kit.
In conversations with two fellow owners with this upgrade, Corey Price and John Buckman, I learned both had experienced the same cracking failure of an internal plastic motor part.
The Vader window lifts are modified units taken from 1990s full-size Ford sedans.
Apparently the plastic failure was common enough that Ford now has a re-designed version that replaces that trouble-prone plastic piece with a full metal casting.
After three-way back and forth discussions, and kicking around a few corrective approaches without much success, Corey Price found the upgraded motors, with the best pricing at Rock Auto.
With the failures seeming to be common, it might be a good proactive action to order replacements, or at least take note of the rock auto part numbers.
