Only had the car 6 months so never needed the aircon until now. The temp on sunday was a dizzy 16 degrees and was quite stuffy in the car so i gave the aircon a whirl. I adjusted the central warm/cold dial to cold, reduced the temp display to 18 degrees and pushed the aircon button, now the air was cool but not aircon ice cool. What i did notice was that once the aircon was activated the revs never rose slightly and i never heard a relay click, althou i was driving so outside noise may have been an influence.
Would my first port of call be to check the relay clicks on and off? how prone are the pumps to failure (98k) on the clock
