OK, wet out to play with the car. The sensor on the side (which was shorted) is for the compressor. The short wire that was made for it was messing up, constantly switching the compressor on and off. I plugged the wires back into the sensor, and it was running great.

The sensor on the top is for the fan. Mine is toast. I am going to replace it (and probably the other one too) when I "rebuild" the system. I am also going to wire in a switch to manually turn the fan on.

I am getting cooler air out of the system (70* at 90* ambient temp) so I still think I need to do the "rebuild", but it's better for the time being. I am planning on replacing the dryer, expansion valve, both sensors on the dryer, and whatever seals I take off. I am also purging, and refilling the system with r-12. Does that sound about right?
