S60 Air Con: - Is it normal...

Aveton Gifford · Apr 2nd, 2012, 19:03

...for the aircon compressor to click on and off every few seconds?? and also it sometimes kicks in with a real thud which I only really seem to notice when it's stationary.

So am I unduly worried or is something about to go bang??

Nope, not normal. Every couple of minutes maybe, every couple of seconds suggests your low on charge and it keeps shutting down due to low pressure.

Wot SD said above ^^^^^ You need yer Air con Re-Gassing & bring up to pressure.... Low A/C Pressure ALWAYS makes the compressor "Cut in & out" more frequently

Thank you chaps, although I'm surprised because it blows nice and cold, but a re-gas it is, I'll get them to do it when they change the cam sensor

mine does the same clicks in and out every 10 secs the gas is full the air is cold so i have left it.so why pay for something that may not need doing yet .

Same here mike, comes on for about 10 secs then off prob every minute or bit more. Had mine gassed in Jan and seems to be ice cold. Maybe a pressure comparison from vida/ vadis is called for?

Thanks again Mike, I'll get them to check it, then if it does need doing they can do it immediately

I did read in the owners manual that it cuts off under high load (accelerating etc) and thought that may have something to do with it!?

Mine also does the "comes on for about 10 secs then off prob every minute or bit more" in this weather. If the inside temp is very hot then the compressor will stay on for a long time.

Over pressure, failing clutch, blocked expansion valve/orifice/tube, or bad temperature sensor may produce same symptoms. Easy enough to check refrigerant charge with A/C manifold with pressure gauge, and check clutch air gap with feeler gauge.
