So it seems like the fourth setting on the heat/ac going out is a big problem with this car and from searching i guess its the resistor in the assembly. In my car I have 1, 2 and 4 with 3 being out. Does that mean that my switch is bad? Would it be easier and/or cheaper for me to just get the whole assembly from a junk yard? Does anyone know how much the switch by itself is? thanks alot

Even though the blower resistor is a very common item to go bad your problem sounds like a switch problem. You will have to get another AC control unit. I two available. Let me know and I'll sell you one if you cannot locate one locally.
