Same part, ive no idea though, guess i have a new part for when i have to replace this one lol.

 

But, the old one has and electrical/mechanical problem that caused the seller to send you a new one - at zero cost and doesn't want the old one back.

That suggests he knows something you do not - I wouldn't put that back on my car ever again... dump it.

 

Meh nothing cuts deeper than logic.

 

Indeed...
