Jim,

I see no movement of a door through the heater resistor hole. Top line to heater core is about the same as the metal crossover, however the return(lower) metal line from the heater core is significantly cooler.

I don't see anything in the 1990 FSM about getting to the door, door actuator or motor. Have you done this on your car? Am I missing something in the FSM?

Thanks again, John
