Does heat come out when you have the max ac on in a 1998 ford expedition?
My mom has been having problems with her heater in her 1998 ford expedition. She took.it in and they say it works if you turn it to heat then turn the other one on max ac? That's how they say the heater works? How could it be hot if its coming from the max ac? But it was cold coming from the heater/panel/floor or just panel or just floor. There trying to say that's how its supposed to be but it would have to use freon if its on max ac? There wanting us to pay them for working on the vehicle but still have no heat but he says it works on max ac? We need to know if that's true and how the heat works througH the vehicle
