The vacuum trick worked! My wife (who couldn't wait for me - I sleep later) got it on the second try. She first used one vacuum we had in the house which did not have strong enough suction, and then a second one. She said it took about 10 seconds.
Saved a lot of dough and, because of Nissan's deplorable engineering, thankfully, didn't have to give them more business.
Again, thanks.
