heard back from the dealer:
"Here's where we are @ on the Explorer... There is no freon in the system. We added dye to the system and traced the leak down to the lines that run to the back for the rear climate control. These lines are almost the length of the entire vehicle. The cradle has to be dropped to get them out. The system will then need to be evacuated and then recharge and also will require and alignment with moving the entire subframe. Bottom line total is $1822.01. "
And to think that I was suckered into buying yet another one back in Dec'17, what the hell was I thinking???
