Mine does not work at all this year. I heard some where that there is a process that you should go through when you first use the a/c each season...I can't recall what that was.
Are you saying the blower fan will only work in speed 1 and 4? If that is the case sounds like a fan control switch, when the blower motor resistor goes you are left with only the highest speed(4). Now if your fan is only working in the high setting(4) I would replace the blower fan motor resistor.

I would check to see what kind of pressures you have in your ac system. Low freon and too high of pressures like a blockage in the system will cause the AC to not work also.
I just went through this with my 96 cobra. I had not driven the car in over 5 months while it was down for the engine work. My AC compressor would not come on at all. My pressures were extremely high, I ended up flushing my AC condensor to remove the blockage. Pressures went down to normal and the AC works perfectly now.
My old car had a similiar problem: ac would work on 1 and 2, fan would only work on 3 and 4... it was the fan relay, there were a couple cracks in two coils (act as resistors, determine fan speed) I got some magnet wire from radioshack and remade the coils, worked great...
Thats o.k., no matter where I turn my switch to, it only comes out of the defroster. If I want the air vents to blow, nope, defrosters.. Anyone have this problem?

Sounds like you have a vacuum problem. When the HVAC system recieves no vacuum it will default to defrost. I would check to see if your vacuum supply line from the engine bay is still hooked up with the vacuum harness.
