I was working for the Nissan truck plant in Smyrna, TN when the change over from Freon to 134A came about. It had to be done before midnight December 31, 1994. Interestingly, that was the exact moment that DuPont's patent ran out on Freon. At the same time, Al Gore, had been preaching about the dangers of Freon on the climate. It just so happened, DuPont had 134A ready to go. Quid Pro Quo?
someone must have told them about it ahead of time...
