I cannot drive it as it has a frozen motor, which is why I am posting al of this to try to figure out the best course with the replacement motor.

Personally I do not think they work, I have not noted any change from before them and after them.

I will say that the back of the van does not seem to get any dirtier than any other part of it.

I would think that suggests there is less a pocket/vacuum behind the van.
