Hi all, lttle background on my air conditioning system first. I have a pajero 2.5 turbo intercooler. Last week the aircon belt broke because the tension pulley had siezed solid. I replaced the bearing but noticed that the pulley on the aircon was a bit loose with lateral play. I ignored it (woops?) and fitted the new belt, tensioned it and the aircon worked fine. Today, however, I was driving along and the temp inside the car started to get noticeably warmer.
Any ideas as to what may be wrong i,e has the system depressurised, clutch gone etc, the belt is still in one piece and the tension is ok.

The clutch is not turning with aircon on but does rotate by hand, I believe that if a low pressure switch is fitted this would stop the clutch from engaging. i am not sure however if my pajero has this cut off switch.



Any help appreciated.
