@chriswellmans It think you're not right if you responded to my video however I think you are spot on when you responded to tonitokiller's problem. When the air compressor clutch air gap is too big the compressor will not engage and there will be no cooling at all. This happens normally after the engine has warmed up. My a/c compressor still works/cools like a charm however engagement and disengagement happens on a short interval.
This type of system is a CCOT (Cycling clutch orifice tube), it engages and disengages because of the pressure in the system and for fuel efficiency. I tested my ac with a multimeter and the voltage is applied in cycles to engage the clutch so its actually working as it should. other ac systems are different as far as I know!
@tonitokiller My clutch still does exactly the same as on the video. Despite that it still cools great (40C outside air temp is no prob). I'm not an expert, but I think you should find out if your A/C clutch disengages because of high or low pressure. Maybe there are some fault codes in the OBD system or maybe there is a possibility to read it directly from the pressure sensors?
A common A/C problem on this car is the evaporator inside the dashboard (rust) or the condensor(damage) in front.
@tonitokiller There was/is no real problem. The A/C cools fine however it seems to turn on/off quite often. So far no repairs have been made and it's still cool in my car whenever I turn the A/C on!
You could also be low on refrigerant or low pressure switch faulty. It is normal for the compressor to cycle but if its not cooling the car I would put some gauges on it and see if its running low on pressure or if its a temp sensor shutting it down. If your low side drops below 30 add some refrigerant.

most likely the air compressor clutch air gap requires adjustment

@kvcuijck Ok your clutch runs fine now? it dosn't stops every 5 sec and run again ?
i still have this problem and my A/C dosn't cool at all, i have checked the air presure and it looks fine , still not have a clue . What can i do ?

@billkeno It's cooling still good. I suspect that there is not enough refrigerant in the system. (Last time serviced in 2007.)

@kvcuijck that exactly would cause that for sure

I now why the clutch disengages after some time. However the time between engagement and disengagement is short. I think it needs servicing.

hey, that is normal.
I checked my car, it's the same. You can read in your manual why it is disengaging after some time..
