Air Con Wierdness

[jonny]

Would have though it quite possible, as the aircon will effect the idle revs of the car as it cuts in and out and the fact that it needs gassing and is therefore not producing any cold air doesn\'t mean that trying to run the aircon isn\'t loading the engine.

depends how little gas is in the system?

if its just enough to turn the pressure switch on then it will activate the compressor clutch and kick the fans in as normal but wont actually get cold. the engine will be under load tho, so could cause hunting with Power FC?

if the system is completely empty then the compressor and fans wont cut in so no extra load would be put on the engine?

if the compressor and fans dont cut in try and bridge the pressure switch connector with the engine running and see if it works then? if so it could just need a regas?

If the system is depressurised, the compressor won\'t cut in but the fans still run.

surely the fans are linked to the compressor by the relay so will only work if the compressor does?

i\'ve removed the aircon from my FD so am only going from previous HONDA experience?............

the fans only work if the compressor does on hondas yeah irc from my integra days....

As far as I remember, the fans are triggered by the AC button even if the system is depressurised but the compressor won\'t run. It was years ago when mine needed gassing though so I could well be wrong
