squidward: what do you mean by "If 74 has the POA instead of the VIR"?

also, does anyone know if the fan speed switch connector on the back of the AC-heater control unit is different between the AC and non-AC cars? I suspect they are, because I think the blower motor resistors are different, but I'm not sure.
POA means it has one of these at the evaporator outlet, going into the suction of your compressor:


VIR means it has the thermal expansion valve and POA valve all wrapped up into a single monstrosity at the evap inlet/outlet:



BTW, I sent u a PM.
