P.S.
It's all either a scam, and/or it's due to efficiencies of manufacturing...
but there's zero reason in my mind to design cars (most all of them) such that you have to pull the whole dang dash off to change the heater core & evaporator core. "They" want over a grand to do it. It's less than 100 bucks in parts. I've seen people quote dealers charging $1,500 dollars. IDK the real cost, haven't called the dealer, but it won't be cheap with all that labor.
It could all be designed MUCH better. But it isn't....
