How can I get into spray the evaporator with some A/C cleaner? Is the best access through the blower resistor, or somewhere else... and where's the resistor or the "somewhere else" located if that's the best spot?

Thanks,

 

Evaporator cleaner? The stuff to clean the outside or the stuff to flush the inside? I assume to clean the outside of the evaporator. Blower resistor hole is good if you have the spray type. Through the cowl on the hood is gonna be better.
