If the motor draws exeessive current: Try to turn the compressor by hand. There are multiple forums dedicated to the same issue. I have a Ducane heat pump. The compressor will not run without jumper wires from the battery. Look up the ambient temp and it will show you the pressure you'll see in the system. When the AC is on, the compressor clutch activates, wherein the drive belt on the engine now turns the compressor which in turn is compressing refrigerant so you can be nice and cold. :o As I was driving yesterday, the A/C on my 1998 Lexus ES-300 stopped blowing cold air.
