Also when I go from air conditioning back to heat I briefly smell radiator fluid. Since heat and AC are separate systems what could cause that?
A man who worked at a Ford assembly plant says it takes just a few minutes to install a dash unit at the factory.
It seems like stupid design when you have to pay for 7 or more hours of labor just to take out a simple heater core. My shop says some cars require 12 hours labor just to get the heater core out.
When the dash is taken in and out on a older car, is there a significant chance that wires and vacuum tubes will get messed up and not work right?
