RPM surge when A/C is switched.

RE: RPM surge when A/C is switched.
yes.its just below the alternater driven by the belt.AC selected to on and the fan speed was just no:1.outside temp was ard 19 degrees.Normally the RPM goes erratic worst when the outside temp is hot.during cold weather is not that bad,but still affects the RPM.
i look at the compressor for the clicking sound tomorow again.
thanks Tech!!!

RE: RPM surge when A/C is switched.
Sorry tech Don"t really understand what is vacumm leak.can u explain?
initially i tot may be it was low on gas or leak.i went to the mechanic to service and they said was fine.
we can narrow down the fault to just the AC sys now which is causing the erratic RPM.The loud 'bong' sound and the hissing/crackling gas sound i can hear when in the car when the AC is turned on really sounds unusual. or there must be a sensor some where is faulty.Lets hope its not the compressor.......

But whenever i switched on AC the compressors starts with a loud 'bong' sound,like as if the compressor sounds like it's over loaded followed by the hissing gas sound being pumped by the compressor(is quite loud when you're in the car).whenever the bong sound comes on from the compressor that is the time the rpm surge and the car feels like losing power and slight vibration from the car.
Basic car AC sys comprises of a compressor,evaporator,condenser ,expansion valve and.......did i miss out anything.If a clogged or faulty condenser will it cause clogging of the freon sys (pipelines)causing the hissing sound?I don't think is a faulty climate control module because the AC works quite fine.

Is the orifice tube which is in the high pressure pipe located in the engine bay?Becos i can only see some rubber and copper tubes near the fire wall.

The orface tube is plastic with screen in it.
I will have to check tomorrow on the Gap spec.
