Hey Bill, maybe this part will work on your car. I looked for the 370Z part, thinking it might be cheaper than an Infinity part. It's online for about 26 bucks. Search for this "Damper 685131EA0A". It seems the box itself is pretty easy to remove. Open it. Pull on it in an upward motion to unpop the lower left and right hand corners. Twist it to clear the tabs and pull it out. The remaining connection I think will be your damper. There are videos on Youtube for changing your "infinity g37 coupe cabin air filter" and it shows you how to remove the glove box (the filter is behind). Hmm, maybe replace your filter while you're in there!
Good luck with the damper and with selling your VW
