if i`m guesing right here you can`t get the ac kompressor to work?
there is a low pressure sensor on the system that will cut power to the clutch if the gas pressure will get to low, this to protect the kompressor that will break down if run without gas.
try to bypass the sensor with a bit of cabel in the conector to the sensor, this needs to be done while the car is running for you to hear the kompressor and fast disconnect it again.
don`t run for more than a couple of seconds.
if this works you have a leak in the ac system that causes low pressure or a faulty sensor, either way you need to have the system refilled and searched for leaks.
a weak point in these cars ac system is the A/C reciever drier, it tends to rust.
