Howard,

Thanks for that. Since I am using a Sanden compressor up front, with new lines, new condenser etc, I will add the safety switch as needed. Probably a trinary switch so I can add a fan later if needed if required. You know how the Calif summers and traffic go together.

I just need to have the evaporator checked for leaks, and then I'll probably replace the old dryer and expansion value with newer ones as I don't know the condition of those. I'll just add a thermostat to the mix which for compressor clutch that will be set to a preset temp. Figure if it gets too cold, then the blowers can be set to low, or just one blower can be left on. Basically, the thermostat is there to keep the evaporator from freezing up.

Is there anyway to test the evaporator for leaks at home? I am sure the most expensive piece in this endeavor is going to be getting those long A/C lines made up.

The rear defroster while probably never used that much except for an early morning car show run here in Calif in the winter months. But it would be useful if I end up relocating to the midwest next year.
