Okay, it is my understanding that "NORM" A/C is drawing hot outside air from the cowl, through the evaporator, and then into the cab.
"MAX" A/C closes a vacuum-operated door and then re-circulates the in-cab air through the evaporator and back into the cab.
My question is --- from where inside the cab is this air entering the blower stream ??
Also, I discovered that my little vacuum-operated gizmo, located under the hood, just above the blower housing, was just barely moving, maybe 1/8" travel, when MAX A/C was selected.
I plugged the line, removed the vacuum-solenoid, and zip-tied the door handle in what I think/hope is the CLOSED position; that is, with the operating-rod/handle pulled against the solenoid mounting surface.
As best I could tell, when I selected MAX A/C, the solenoid was trying to pull inward, and when OFF or NORM were selected, the solenoid rod extended; is this correct ??
There is nothing wrong with the amount of vacuum on that line; the problem is with the solenoid itself.
Thanks.
