The KLIMA relay will disengage the compressor if it detects a speed difference between the engine and the a/c compressor. This is designed to prevent the belt from being damaged in the event of an a/c compressor lock up.
Sometimes if the KLIMA relay has internal problems it can kick off and shut down the compressor.
One way to test and see if the KLIMA is the problem is to bypass it with a standard relay. This takes some work but can be done.
Another issue you might be seeing is a faulty evaporator temperature sensor. If the sensor is bad it could be prematurely shutting down the a/c compressor.
Sorting out the vacuum system is a must though. If you dont have all the pods working well then you wont get air in the right places.
