Car Forum / Volvo Cars / June 2006V70 aircon pump life?
I have a V70 Classic, 150,000 on the clock, with aircon, and which despite re-gassing still only works (although very well) for about a few minutes then goes off for about 30 mins (suggests something cooling down / warming up ?) Someone has said that a "fixed orifice filter" needs to be checked, and is likely to be full of metal shavings / swarf as the compressor pump has come to the end and these bits are from its internals. This means a new compressor apparently. Can anyone confirm this and what are the options if this is so ? i.e. re-conned unit, pattern unit, salvaged unit from a vehicle a bit younger (75,000 miles ?) Thanks Nick > I have a V70 Classic, 150,000 on the clock, with aircon, and which despite > re-gassing still only works (although very well) for about a few minutes [quoted text clipped - 9 lines] > re-conned unit, pattern unit, salvaged unit from a vehicle a bit younger > (75,000 miles ?) Firstly btpass the superheat cutout switch on the back of the compressor- very common ailment on the V70. If this doesnt sort it, then you;ll be needing to check the HP sensor, which needs the use of a FCR on the 70 series i'm afriad. Manual a/c or climate?? Any flashing recirc lights?

Hi Tim, Its a manual a/c - not seen any flashing recirc lights or any lights flashing. Where would I find the HP sensor and what is an FCR? Sorry for more questions - much appreciate your help Nick > >> I have a V70 Classic, 150,000 on the clock, with aircon, and which > >> despite [quoted text clipped - 31 lines] > Sorry for more questions - much appreciate your help > Nick FCR= fault code reader / scan tool. The ECU reads actual pressure of the a/c system and regualtes the condensor fan and compressor clutch accordingly. This is the proper method of charging the a/c too, though you can do it 90% accurate via weight. The superheat or overheat cutout switch is on the back of the compressor and has two wires. The connectors are such that you can disconnect both ends of the switch, then hook the feed from the car direct to the compressor clutch, thus by passing the switch. This is your first port of call.
