Hi,
if the klima is working, it should prevent damaging the clutch....that is what i understand..there is test in the maintenance CD for the klima...they say: spray a jet of water at the belt at the Ac compressor, while the AC is on...the klima should detect such little slipping and cut the compressor...if not, replace klima (after doing other tests)...
SO, I am not sure if the failure you have is due to not working klima or this is something could happen with the klima working!!??
Somebody might clearify this,
thanks
