Shouldn't be a big beal to replace. Just about any auto parts store has replacement motors. I'd have to see it, but I think it's behind the glovebox.....remove the plastic push-pins, then the cover behind the box, then unbolt and withdraw the motor. Once they squeal, don't even bother trying to oil them, as the bushings are wobbled. Any time we tried, the vibration that ensued from the armature wobbling in the bushings was unaceptable.
