Hmmm....Good to know. The problem still remains though. There's not gonna be any R134A to use. Like I've been sqawking about all along. R134A is going bye bye. Keep a sharp eye on the price of 134. That's when you know the powers that be stopped producing it. You CANNOT stuff 1234yf into an R134A system. Not compatible. Then the gold rush begins on what's left of 134 in stock. Been there in the late 70's-80's. SAME situation. Then the car manufactures force you to buy a car using 1234yz. It's the same old scam with the chemical companies and the bean counters. They don't care about any ozone layer. They already admitted switching to R134A made no improvement to the ozone layer. Complete scam,,,again....And the poor schmuck driver gets it dry...,,again
